Muffler - help, please!

PittVXr: Thank you!

I'm on summitracing.com, and I found the Dynomax Super turbo mufflers, but there are 84 of them... This is a great example of what I mean when I say I'm not a gear-head. If I knew, for example, that a "2 1/4 in. Inlet -- 2 1/4 in. Outlet" is the right or wrong size, I could narrow it down. Same with "14.000 in. Case Length," and "18.500 in. Overall Length," and so on.

I have no problem doing my homework--I'm eager to learn, and I want to make an informed decision, but holy crap, I feel like a fish out of water here.

I went with a 20" case, Offset Inlet, and a Center Outlet. That was recommended to me by another member who used the Super turbo. It fits just fine where the old muffler was.



I also went with a 2.50 inch pipe which is slightly larger than stock. For the record I am not sure what diameter the stock exhaust pipe is, but I am sure someone here knows. (I THINK it is 2.25")

Awesome - thank you!

Did you buy the Dynomax Performance 17748 ? When I narrowed down the results to match what you stated, I came up with just one remaining, so I assume that's the one.

OK, and now for probably the dumbest question I've asked (so far): do I need to buy a tailpipe - is that separate?

I just put on a Dynomax Super Turbo 17747. The body is 20". They do not offer stainless.
I replaced the tail pipe with stainless. I used a 2 1/2" and welded it to the stock tip to match. The stock size is about 2". The shop bent up a piece to match the stock curves. I stayed with 2 1/4 on the muffler to minimize the sound.
The sound is less than my Power Vault I, which had grown too loud. I tried a Flowmax and I found it much too loud. I hit a resonance at 2500 rpm.
