hay guys i wanted to get the Stillen true-dual cat back system. i wanted to know if it will work with my stock 04 AT coupe .i see there are 2 kinds of Exhausts 1 Stillen true-dual cat back system and 1 reguler cat back system what is the diff. and what will work for my stock coupe?
Is the Stillen true-dual cat back system loud? how much lowder then stock?

 

If im not mistaken, a true dual isnt going to help much, as our cars need some of the backpressure provided by our exhausts.

Hope that helps a bit at least.

 

bump

 

I think you're mistaking the sedan true-dual exhaust with coupe. I believe all the after market exhaust for Coupe are all true dual from header back.

 

yea it will fit

 

Sitting here looking at my Stillen catalog, they make
a true-dual system and a single (cheaper). Everything G35 sells one of the systems at a good price, check it out! Anyone that owns a true-dual
Stillen system loves the sound.....(I sold one).
