Installed a Spintech Sportsman muffler (review)

[v8Toilet]

This past Saturday I installed a Spintech Sportsman XL muffler in place of the factory muffler. I wanted a little throatier sound and a little more power and mileage wouldn't hurt either. I bought a 2-1/2” center inlet and 2-1/2” side exit and installed it myself.

The sound summed up in one word is awesome! It's the perfect compromise between all out obnoxiously loud and factory quiet. It has a deep mellow sound at idle that can barely be heard from inside the cabin. I expected it to be louder when I first started it up. It sounds most like a muted Borla at idle, very deep and mellow but it’s still distinct.

I've had the TRD dual exhaust before so I'll compare it to that. It's quieter or about as quiet as the TRD at idle but when you get on it, it becomes louder and sounds way better. It doesn't drone nearly as bad at 2000 rpm like the TRD dual exhaust did. During normal driving under 2500 rpm it produces a gratifying deep throaty sound that is just perfect. Not too loud and not too quiet. When you give it a lot of throttle like accelerating up a highway on-ramp it gets really loud under 2500 RPM, then starts to wail at 3000 rpm and really wails above that producing the most awesome sound I think you could get from this engine. On the highway you can hardly hear it at a 65-70 mph cruise and light throttle, which is perfect and there is no drone.

As far as power is concerned I can't really say until I put it on the Dyno March 29th. The but-O-meter as many of you know is highly inaccurate. I think there might be a small power increase but we'll see. If anything there is no difference for now.

Cost was only $99 + $5 for a short 2-3/8 pipe as an adaptor to make it fit the 2-1/4” stock pipe.

Soon to come I will cut the stock muffler in half so that TS members can see what it looks like inside. We’ll see just how restrictive this muffler is!

Here is a picture of the Spintech muffler painted black. It's built like a tank. The quality is first rate.

Hey v8Toilet do you know if I can use the sport truck SUV muffler
or the sportman street mufflers with the hiflow cats I have a 2003 V6

I don't see why not! All you have to do is go to their website @ http://www.spintechmufflers.com and look up the muffler that best matches the size of the stock mufflers length, order it, and then have a muffler fabrication shop cut out the old and install the Spintech. You could also do it yourself but if I had to do it again I would just have someone else do it. If you can get a 2.25" inlet diameter and 2.25" outlet diameter than get it and if not than get the next size up. The stock pipe size is 2.25" on the v8 engine. Don’t get a dual outlet muffler; I feel the singe outlet will give you just as much power without hurting low-end torque, which is important in a pickup truck. It also makes everyday normal driving more gratifying when you have good low-end torque.

Funny thing is I spent way more money for the TRD dual exhaust and lost my low-end torque so much so I couldn’t spin the dam tires even in a turn. The TRD exhaust didn’t sound as good in my opinion and droned at 2000 rpm on the highway.

They sell the aluminized Spintech muffler for around $99 each and the stainless steel muffler for about $80 more or $180.

By the way since I reset the computer and added the TRD filter I think there has definitely been an increase in power especially in low end and the midrange.

I don't think you need high flow catalytic converters! I've seen tests in Hot Rod magazine where OEM GM converters out flowed so called high flow aftermarket converters. Changing over the like new stock converters is a waste of money in my opinion and won't net you anything or very little.

I think the biggest restrictions in the exhaust are the exhaust manifolds and the muffler.

I'm glad you like the sound and power!
Doesn't it sound like a muscle car?

[v8Toilet]

O-yeah!

What is the part number you ordered?

#3332XL but it's 2.5" in and 2.5 inch out.

The size of the muffler relates to the sound level. Spintech's big "Truck RV" muffler will be quieter, and their "Sportsmen Street" muffler will be louder.

What is the stock diameter piping on a V6 and would I benifit if I go with 2 1/2 inch Diameter pipes

[Tundra Guy]

I noticed some have stated the stock 4.7L V8 Tundra pipes were 2.25 inch, but others have stated 2.5 inch (and did not mention the mis-fit issue). Also, virtually all aftermarket cat-back kits for this engine are either 2.5 or 3.0 inches - adding to my confusion. And, obviously, you had to use adapters to go down from 2.5 to 2.25 inches during install, so I am "befuzzled". For the 4.7L V8 Tundra (2000-2006) are there varying stock pipe diameters by year, or what? Some posts have stated they used the SpinTech PN 3333 which is 2.5 inches in and out. You stated you used the 3332XL which is also 2.5 in and out- but had to reduce to install it. SpinTech's brochure shows the 3222 and 3222XL (as well as others) with 2.25 inch pipes, but no one has ever mentioned using any SpinTech muffler part numbers that are 2.25 inches in the forum (that I have seen, anyway), which seems odd. Still, the prevailing citations still indicate a 2.25 inch stock piping. Before I spend my money, is there any reason why I would not want to buy a SpinTech with 2.25 inch pipes, if that is the required direct fit solution? Can anyone shed some additional light on this subject before I buy the wrong muffler inlet size? I am wondering if this is a O.D. vs. I.D. issue? Any help is appreciated. Thanks to all on this great forum.

I just got the 2.5" IN/OUT size Sportsman XL and then had the shop use the 2.25" stock pipe using lots of welding stick to fill it the gaps then doing a nice seal all around. Can't remember what model I got but its the 2.5" size. Get them to take off the resonator too and replace with stock piping diameter in place there (I think mine could be louder/nastier without the resonator on: Others have said so too on previous threads).

Last.. Get their 304 Stainless Steel version directly from Spintech. Mine was twice as much in price as the Mild Steel they regularly use. It will hold up better.

just installed one in my 08 sequoia. didnt want it too loud but wanted to know it was there. this is the perfect exhaust just what i wanted and man does it howl when you get on it.
