Who has this set up on their car I really like how the OEM exhaust sounds but want more air to flow through. Can any tell me what HFC brand used to fit the aftermarket brand y-pipe, so that they can fit on the rest of the OEM parts.
If you have sound clips taht would be great.

 

If you're looking for a stock-esque sound but want more flow look into the Nismo exhaust system. The sound is very similar, just amplified.

 

Right now i have test pipes and a ypipe. It sounded fine without the test pipes but the rasp is unbearable for me. Sounds like a tin can civic down low but up top its wonderful. I have HFC's coming but i wont be able to tell because i also have an exhaust on its way....
