You will definitely hear your motor roar louder with short headers.

 

so my set up now is stock headers Motordyne ART test pipes and Borla catback exhaust. The Borla is 2.25 i.d and testpipes are 2.6 i.d I thought replacing my H pipe with a bigger piping would help but it looks like my restriction is at the headers. I love the growl of the borla so im not looking to replace it with a new one, and headers are so expensive for "minimal gains" ahh I don't know what to do!!!
