Has anyone ever made their own exhaust system as in a DIY. If so or there are any threads on it cause I can't find anything. Does anyone know where on the internet they sell exhaust pipe to make your own, or a place where they will make one for me. Thanks for any information.

 

[Mr. Creosote]

Yes, you can buy prebent pipes called "mandrels".

You can use a

to cut pieces off these mandrels to build the curves needed to get around the differential etc,

welding the pieces together. I have done several complete exhausts like this over the years, with the latest being the front portion of the Borla cat back, which needed to be rebuilt shorter for the RCSB.

Welding is the problem for me. I cut mine off (

) and installed two glasspacks with turndowns before the axle. It drones like crazy1650-1850rpms). I am considering have a local shop run the pipes longer out the back, I think it might help. I was considering purchasing a welder and doing my own, but don't want to spend the $200 at this point.

Flowmaster has prebent kits (order a pair for duals) for most cars and trucks. Hearthrob also sells kits. See if either offers an assortment. You can pick and choose what you need. If you have a buddy with a lift it makes it easier. Tack ervything in palce (try to use flanges so it will come apart later. Then remove it and weld it solid or take it to a shop and have them weld it then bolt it up to the flanges.

Or take a drive south this summer to the four corners and give me a call. We will hook you up with almost anything you want, mandrel bent, stainless or aluminized, Borla, magnaflow, flowmaster, flowpro, spintech or eh gad cherry bomb.

I made my own 08 5.7 tundra exhaust system, and it works great. no resonance(humming) search "$180 Cat Back System" for pictures.

 

[Mr. Creosote]

I remember that. You are a genius. :first:

 

[Mr. Creosote]

This can be fixed by making your own Helmholtz resonator. Search on "Helmholtz".

 

[tundraduckhunter]

I have search for the $180 Cat Back System and I can't find it. Does anyone have a direct link to it.

You can search "All threads started by wells service" and you will find it. Essentially he took the stock muffler, opened up two holes on the back side where the pipes come in and inserted pipes in there, had the center hole welded up.

Yeah, I saw your resonator you had on the "drone-master" as you called it. I don't have a welder so, I think it is out of the question. I wonder if running them out the back would be helpful in reducing drone? Seems like others have done it and it will be helpful. There is a local shop that is advertising duals for $150, so may take them up on that offer.

 

[Mr. Creosote]

Changing the length of the tube does not usually remove drone per se. It changes the frequency of the drone. Running a longer tailpipe will make the drone appear at a lower rpm or cruising speed. If it drones at 60 mph now, making the tailpipe longer might make it drone at 50 mph instead. That being said, sometimes shifting the drone frequency can effectively stop the drone if the new drone point is somewhere your engine never (or rarely) gets to in terms of rpms.

150 for duals is cheap. take it.

i paid 350 for my true duals at my usual exhaust place, two flowmasters and two rolled stainless tips. mine was a great price IMO and ive been going to them for years. i think if u can do any exhaust work for less than 200, its a miracle. go for it.

 

[thumbster]

How about this - h-pipe-exhaust-project-done

 

[keepontrukin]

I gotta exhaust question, so i figured I'd post it here instead of starting a new thread. I would like get 2 Flowmaster 40 series and have the 2 tailpipes exit out where the stock tailpipe is located. Is there enough clearance under there for that setup?

 

[Mr. Creosote]

The dual tailpipes should not be a problem, as some cat back manufacturers offer the exact same thing on the gen 2 Tundra. The only part you might have to take care with would be the dual mufflers. Two of them would probably have to be mounted long side vertical, which could protrude downward too much if you are not careful enough with the system design. That said, I have seen several do this exact thing, so there is no reason it shouldn't work fine. :nod:

 

[Barney_Fife]

just use jc whitney flexible exhaust pipe hahahahhahahaha bend it wherever u wanna put it.

EZ to fit them side by side vertically. of course mine are split out to run out the back but there would be no problem in running two flowmasters like this and run the pipes side by side out the stock exit loc.

:ts: I do have the TRD sway bar, so I hope that doesn't make a difference. How does your dual flowmasters sound? I've had Flowmaster 40's on all my previous trucks, but this will be the first time I'll put on 2 of them. The louder the better, I'm still young.

 

[Barney_Fife]

dunno bout the sway bar. as u can see i dont have one. i love the sound. its a nice tone while driving, u can hear it when u get on it, sounds great from outside but never annoying. i had SLP on a C5 corvette and it was downright obnoxious and MBRP on a V6 03 tiburon GT and it resonated so bad inside.... but this exhaust setup is great. never had an issue with duals anywya. my 77 heavy half pickup had true duals, no cats, and short glasspacks...and man it was loud but sounded great.

Yah, I doubt they will include stainless tips in that price. I am definitely going to give them a call.
