I am going to put a dynomax bullet in my I-Pipe so it be a dynomouth exhaust but I dont know what how long it should be.Does the length of it matter with performance?

I don't think the size matter for performance, mostly sound. I run the 12" long bullet on custom 3" exhaust that dumps at the rear axel. Pretty loud, but that the way I like it.

Why put it in the I-pipe? Wouldnt you swap the muffler out for the bullet? Thats the way the loudmouth, borlmouth swap is.

FWIW, the longer the muffler, the quiter its going to be. And if your stock catback then 2 1/2 is what you want. If not stock then its most likley a 3in peice.

I installed a Dynomax Bullet inplae of my catalytic converter and it only lasted a year. It cant withstand the heat just post headers and the insides deformed and eventually came apart. I then just installed a 3" test pipe of which I am still testing.

With the bullets the longer it is the quiter it will be. (in bullet quitness that is) Here is a vid for you. ORY, 3in all the way back to a bullet in place of the factory muffler. 18in bullet on car
