I just intalled a 2.5" Dynamax Bullet on the Formula. It's dumped where the cat once set. It sounds absolutely hideous. The exhaust pulse is enough to make me wanna throw up. I need some advice on which brand to go with that offers good flow and a relatively quiet sound. Relatively meaning the basically stock sound with no cats. Thanks.

 

Stumped? Me too.

 

so you took out the cat and just put a bullet in place of it with nothing else? i bet it does sound like crap. you need an aftermarket catback and possibly install a cutout if youd like. stock sound? the 2otl is pretty quiet.

 

I had the cat cut out for a long time because it was clogged. So I decided to put the Bullet where the cat was. And it sounds awful.
