I've been seriously considering going with the "Aero Exhaust" but i'm still not sure. If anybody has it, or knows anything about it i'd really like some feed back on it thanks.

What attracted you to it ?

The idea behind it is that it creates a vacuum affect which tells the computer it needs more air and there for creating more HP. I guess what i'm looking for is performance over anything else. You know anything on it?

:tu:
what he said, buy one for the sound, not minimal hps.

The aeroturbine muffler is not really that effective of a muffler. I've heard one on a Tundra and thought it sounded like a rusted apart exhaust system.

Sounds like marketing horse $#!+ to me. How is a muffler supposed to create a vacuum? Exhaust gasses (pressure) is being forced through the muffler. What force of suction would be created by the muffler that could be pulling the exhaust gasses out that are greater than the engine's pushing the exhaust gasses out? In other words, suction created is greater than the pressure pushing out? It is about as silly as the hoods that are supposed to create a ram-air effect --> Those are all about looks, not extra HP.

With regards to exhaust systems, I would look towards some of the more reputable systems out there.

The aero's actually work quite well on diesels. Lots of documentation on some of the diesel forums.

I had one on my 07 5.7 and i loved it. I just sold it to someone else and put the stock one back on mine and i noticed there was a power loss by putting the stock one back on. I would definitly go with the 3030XL with the built in resinator. It sounds the best out of anything else and when your on the freeway you dont hear it at all.

I agree - great turbo-diesel muffler. On a gas engine it's a different story. Diesel engines don't have those sharp exhaust pulses, especially when further dampened by a turbo in the exhaust stream. Gas engines need more high frequency attenuation to get a quieter exhaust note.

If you run a properly designed resonator with the 3030 aero muffler, you'd be at a tolerable noise level, but I'm willing to bet you still won't be in compliance with most state's exhaust noise limits. I'm already far over the limits with my dumped magnaflows. I can only imagine how loud a dumped aeroturbine would be on a 5.7 Tundra :rockon:

There not that loud. But you definitly have to run a tailpipe. I wish i got a sound clip of mine.

I installed the 2525 resonated version on my 2004 DC 4.7 and I liked the exhaust tone right away. However, we also cut out the stock resonator which proved to be a major mistake. The drone in the cab at 70-75 mph was very prominent. It drove my wife insane and me in the process. We solved it by putting a glass pack in where the original resonator had been. Now the truck has a nice sound to it and freeway travel is just fine.

As far as a horsepower gain I could not tell you. I did not dyno it but it did seem that I ended up ten miles over the speed limit a lot faster than usual.

The patent for the Aero turbine is based in part upon the ring inside that acts like an airfoil. It splits the incoming air stream and directs the outer portion of it along the walls of the muffler while the inner core of the exhaust stream continues to travel in a straight path. Since the outer layer of exhaust gas must travel a longer distance than the inner core of exhaust gas it has to speed up to catch up to the inner column of exhaust gas before it recombines with it. In theory this holds some validity but as an owner of an aero turbine I cannot say that it would be a measurable difference on a gasoline engine. I have read and heard that diesel owners are able to measure a significant difference in performance with the aero turbine.

I am not disappointed with it, but I am not sure I would buy it again. I think I would try out another exhaust to find the all elusive "perfect tone."

I had a 2525 on my 2000 4.7 with the stock resonator and it sounded great. It also had the most power out of the 3 systems I have been through. First was a magnaflow...there went the power. But it was to large so that was most of the problem, sounded good though. I managed to crack the 2525 down in baja and put a flowmaster on. The low end and throttle response was improved but mid and top ends suffered, sounds good though. That has been on there since. But they warrantied the 2525, so that has been wraped up new in the garage for years now.

Now I want to do the 5.7 finally ( I took the intake off till I got the exhaust in). And I want to go with a Turbine. I could use the 2525 and buy another and go true duals (out the side) or go with the 3030xl (out the side). I would prefer the single outlet and the 3030xl has a built in resonator.

wwh06, Did you go with a 2.25" to 3" Y into it? To me seems like a wierd setup. How did it work out? Why did you take it off? And do you think it would be too loud out the side? Thoughts people?

The 3030XL has a built in resonator, thats what it's so much longer.

I love mine. I dumped it right after the axle. Most importantly NO DRONE!

Yes i did run a two into one into the muffler. I had mine dump out after the rearend. Its an excellent muffler and i sold many at my work cause i would show people how mine sounded and they liked it.I have the 5.7 crewmax and i wouldn't recommend dumping it in front of the rear wheel. But this was by far the best sounding exhaust i have ever heard. I only took it of cause i filed lemon law on my truck and i put it on his double cab and absolutly loves it.

We solved it by putting a glass pack in where the original resonator had been. Now the truck has a nice sound to it and freeway travel is just fine.

HighwayLizard. What glass pack did you install to eliminate the drone? I had the 2525xl installed today on my 04 DC and I was grinning ear to ear all the way home. However, there is considerable drone from 1800 to 2200 RPM. I left the stock resonator on and just had the shop install the 2525xl as well as the Aero tip that I purchased. It seems my acceleration is right around that 2000 rpm range and the drone is really considerable.

Did the glass pack completely eliminate the drone, or just quiet it down some? Thanks

Hey Mjunior,

I just looked at this thread and realized you asked me a question several days ago. I am sorry for not catching that sooner. I will call the shop that did mine and ask them what brand and model number they installed.

Read through my thread on the aeroturbine (http://www.tundrasolutions.com/forums/1gen-tundra/149302-aero-turbine-exhaust/) for full details of the whole ordeal. It eliminated the drone - this according to my wife who is highly, irrationally, overly sensitive to these types of things. We ran 1400 miles down and back to the Keys without a single complaint.

If you have you stock resonator and are experiencing drone in the physical sense (rather than just the auditory sense) then you may have a problem. However, my stock resonator was only about 6 inches in length and the new glass pack is at least two feet long. I just went outside and eyeballed it but did not slap a tape measure on it. My guess is that the longer resonator (glass pack) serves to cancel out the drone.

Your exhaust is much like a slide trombone. The distance from the engine to the resonator will have an affect on sound based on rpm (the speed of the gas moving through it). This is the same for the distance between the resonator and the muffler as well as the distance from the muffler to where the exhaust exits. The size and location of the resonator and muffler along the exhaust path all come into play with noise level (volume), tone, and drone (a physical experience beyond words). As with all systems there is a resonant frequency that when reached will produce either a desirable noise or a painful experience.

I have pictures of the install posted on my profile if you want to check them out.

HighwayLizard

Thanks so much for your reply. I read your original threat on this exhaust. I actually read it over and over again many times, and from your description of the exhaust, it sounded like it was exactly the thing I was looking for. I can honestly say its the sound I was looking for. I was grinning from ear to ear and giggling like a schoolgirl on the drive home after having it installed.

It drones from 1800 to 2100rpm. It doesn't manifest itself physically in the cab with ratting windows or door panels, but rather it's an uncomfortable audible drone. Very hard on the ears. I looked at my resonator again last night, and it sounds like it may be different from the oem resonator you had. Mine looks to be about a foot long, and its right under the passenger side seats. I was thinking about removing everything from just before the resonaor all the way back to the muffler and replacing it with the glasspack and 2.5" tubing. I'm hoping that will help get rid of that drone. From what you described in your thread, that may take care of the problem. At least that's my hope. The other option I was thinking about was getting an Aero resonator and placing that just behind the oem resonator. I'm not sure if that would help or just further restrict the system at all.

My goal is to get rid of that drone and retain the sound of the system as it is now. I really don't want to lose the growl that the exhaust has now. I'm still grinnin from ear to ear every time I start the thing up.

Thanks for checking on that part for me. I really do appreciate it.

Hey MJ,

I called the shop that did my glass pack and he could not remember the name off the top of his head but he did tell me they get their glass packs out of Kentucky (like that is going to help you at all).

He did say that nearly all glass packs are the same. He also said you will want to keep the inlet and outlet the same diameter in comparison to each other as well as the size of the exhaust pipe. For example, if your exhaust pipe is 2.25 inches then you will want to keep the inlet and outlet of the glass pack at 2.25 inches as well.

Sorry this is not more specific but it was all I could come up with for you. Let me know how it works out for you.

Thanks HighwayLizard. Guess I'll have to do a little research on it. I will post back if and when I can get this sorted out.

Hey MJ,

Just had duals ("Foolies") put on from the exit of the Aero Turbine and then out each side. The pipes have stainless tips just under the corners of the rear bumper. Really looks and sounds great. There is a y-pipe that splits the exhaust as it comes out of the Aero and then two pipes over the axle. I will get pictures posted up tomorrow.

I know this set-up is not supposed to yield any additional power but I swear the rear end of the truck hogs down and digs in when I stomp on it. I am thinking the Aero Turbine with this set-up may be giving me some gains. The only way to know is to dyno it. In the meantime I am going to see if it has any effect on the MPG for the truck.

Thanks HighwayLizard. That may be a project on my truck for a different day. I would love to see some pics. I'm going on tomorrow morning to have the oem resonator cut out and an 18" glasspack installed in it's place. With the experience you have had, I am hopeful that this will eliminate that drone without altering the sound of the exhaust too much.

Definitely post some pics of your dual setup.
mj

Good news!! I went to the muffler place this morning and had the oem resonator cut out. They installed in it's place an 18" glasspack. This has eliminated the drone in the cab about 99%. There is still a slight resonance right at 2000 rpm, but it is noticeably less then before. I am extremely happy with this result. The exhaust tone remains almost unchanged. If I step on it, I can still hear that growl in the cab under acceleration, but when cruising, it's actually pretty quiet and unobtrusive. We stopped at a parking lot a short ways away from the shop and I got out to listen to the sound coming from the tip. I reved the engine and my son said it sounds like a race car. Pretty high praise coming from a 5 year old.

So, drone is gone, growl remains. Very happy with the results of this mod.

mj

Video/soundclip please...
If possible outside and inside. Thanks!

Hey MJ,

Here are the pictures I promised you. Still really like it. Midlife crises be damned - I feel like I am 17 again. Really glad the glass pack seems to have taken care of things for you. I was pretty sure that since you were running the same set-up that you would need to do what I did to take care of it.

I know it sounds great - I love my sound. The "foolies" really make it sound nice. I think I have found what I was looking for when I started modifying my exhaust. When I really get on it the truck just flies off the line and at a certain RPM (cannot look at the Tach while I am doing this) there is this new sound from the rear of the truck - almost like a jet exhaust. I need to find someone here who can record it so I can post a sound clip but it is very different from anything I have ever heard before under flat out full bore hard accerlation. Not complaining, just unexpected.

Isn't that from the aero turbine? They make this sound on diesels.

Yes, sound clips would be very nice, especially in the cab cruising at 60-70MPH. Thanks!

I am not sure if this is coming from the turbine. I have wound the truck out before but never heard this sound.

I am going to need some advice on how to get a good sound clip as this is something I have never done before. My wife's digital camera takes crappy sound recordings. Maybe we can make a run up to Michigan to see the in-laws. My sister-in-law has a production level video camera that she makes movies of weddings and birthdays with so maybe she can record the truck running by as well as the in cab sound level.

HighwayLizard

That's a good looking system you have in there. That may be something I will do sometime down the line as well. I would love to hear what it sounds like. I will attempt to get a couple vids of my system as requested. Maybe this weekend since it's supposed to be nice here.

mj

Just an update and some more observations:

That new sound kicks in at 3800 RPM.

I have to brag on the exhaust set-up as it is exactly what I have been trying to achieve. The sound at idle is just perfect, nice low just barely noticeable growl. Accelerating smoothly off the line it growls enough to let you know it is there. Coasting, the exhaust bubbles rumbles like the camaro I was in love with as a kid (the US Marine up the street from my parent's house where I grew up had one and I always knew when he was home on leave).

Hard accelerations the truck just sounds like one mean son of a b!tch. Very aggressive. If I really get on it it sounds like it is very angry. I love it. Gunning it at the lights turns heads. When going under over passes in the city I pop it in neutral and gun it several times. The sound is awesome. Under the over passes when I gun it the truck ROARS.

I think this set-up, with the splits off the outlet of the Aero Turbine has actually returned some improved fuel mileage - despite the fact that I am running the piss out of it and not driving like I normally do. I will have to keep an eye on things over a long period of time before I can make a statement to the effect that it is improving my fuel economy. For now, it just seems like it is.

I have JBA headers, no resonator, an Aero muffler and never had a problem with drone. I had alot of drone with my Gibson and Spintech mufflers even WITH the resonator on the truck.

go and youtube username kslyguy808 (me) I posted up clips of my aero exhaust a couple of years ago when I first had it installed...I have since went through two modifications going from single to dual exhaust and three different tip setups. I have posted inside and outside clips of the exhaust.

I will try and get my other videos uploaded of the different tips either tonight or tomorrow after work.

HighwayLizard

If you don't mind my asking, how much did the shop charge you for the "foolie" exhaust setup?

Hey MJ,

Grand total with tax was $255.63 with polished stainless tips. In hindsight I should not have had the tips put on because I cannot keep them clean. Even with the mud flaps they are in the line of fire and just get hammered with all the crap the tires can throw at them. If I had it to do over again I would have just had them do an angle cut on the exhaust piping because the piping itself is stainless. I think the tips were right at $60 a piece.

I still love it though and would do it all over again. Make sure you ask around to find out which shop has the best reputation before you have anything done. The shop that did mine has done exhausts that appeared in Hot Rod magazine - I also have had nothing but perfect results from them with anything I have gone to them for.

If you are going to do the foolies make sure to to post up pictures and a sound clip if you can. Hell, post a picture of that seventeen year old grind plastered on your face (foolies should be the antidote to "bitter beer face"). We were supposed to be up in Michigan this week for my father-in-law's birthday and I was going to have my sister-in-law make some videos and audio recordings of the truck because she has a production level camera that she does movies of weddings and birthdays with, but that is not going to happen.

Going through changes here but still plugging ahead in spite of everything.

:ts:Thanks:ts: HighwayLizard. That's actually a good price to complete that system. I may go ahead with that in a few weeks. I'll have to look around and find a reputable shop that does a lot of custom stuff. There are a couple around here that do custom vehicles so I'm sure I won't have a problem finding one. I have the Aero Exhaust tip on the passenger side so I would have to purchase another one for the drivers side. I only paid $40 for the tip from ebay so that's not a big deal either.
I'll get some pics and maybe a video of my system as it is now maybe this weekend as long as the rain holds off.
As far as the pics of me with the grin, well, you're just going to have to imagine it. Nobody wants to see my mug anywhere on the internet.:)

Hey MJ,

Any progress on your exhaust? I am gearing up for the next round of modifications which will be headers and probably a y-pipe.

HighwayLizard

Funny you should ask. I had the "foolie" exhaust done up yesterday morning. I was absolutely giddy with excitement upon picking up the truck. The tone changed a little bit. Its a bit deeper, and definitely has a growl on idle. It really seems to have a wind up on hard acceleration. Deep throaty growl, and it really screams. I told the guy that did the work that this is how it should have come from the factory. On another note, the drone is almost completely gone as well. Don't know if it's because a little more restriction is gone or what.

I have the Y pipe welded on right after the muffer much like yours. I also had him run 2 new 2.5" pipes from the y on back to the tips. Aero Exhaust 2.5 to 3.5 tips on both sides. You can just see them poking out behind the tires. They did a really good job of routing the tubing on the drivers side to keep it far away from the spare. I'll see if I can get some pics put up in the next couple days. Still can't find that darn digital camera.

I hope you don't mind my stealing your setup on this. After 4 1/2 years of ownership, the truck finally has a voice and told me her name.

I have uploaded some pics of my "foolie" exhaust setup as HighwayLizard likes to call it. Pretty accurate name he tagged to it. I love it. Check my garage for the pics. I will attempt to get a couple of better pics as soon as I can locate that stupid digital camera. I'll post a video of the sound as well as soon as I can.

Hey MJ,

I was positive you would love this set-up with your Aero Turbine. I got really lucky in finding the right combination and once I had the "foolies" done up I really felt I had hit the nail on the head as far as sound. This is the sound I have been after since I first got the truck. I am not saying it is any better than anyone else's but as for me I think it is perfect. Everything you mentioned was perfect in my ears. I love the rumble at idle, I love how it winds out and howls, I love how it just screams like a really pissed-off SOB when I stand on it. The tone is perfect, and much like your experience the drone is almost non-existent.

MJ that is one great looking truck. I was going to name my truck but the pending ex Mrs. Lizard never would allow me. Guess I can name her whatever I like now.

No problem and I am nearly as pleased as you are with your results. It is a really good feeling being able to help someone track down whatever they are working on so I sort of feel that I benefited more from the exchange than you may have. By the way you did not steal it from me - I read about it in a post (http://www.tundrasolutions.com/forums/performance-exhaust-systems/145058-glasspacks-and-x-pipe/) by USAFTUNDRA (http://www.tundrasolutions.com/forums/members/usaftundra/) (really great guy here on the forum who is currently on deployment) and I think it was someone he works with at the base that dubbed his set-up "foolies."

I have been wanting to post a sound clip. My sister-in-law has an incredible camera that she uses to make movies of birthdays, weddings and the like and it is like a movie production level camera. I was going to do a couple of passes and also get some clips from in the cab. It looks like it may be awhile before I can get around to doing that.
