I have a Megan header, test pipe, and Cat (test pipe) back. 2.25 I think. On a B16A What can I do to get rid of some of the raspiness?

 

what muffler do you have? Stock? If so, is your test pipe resonated? If not, there's your problem.

 

Its a full Megan racing cat back. Including the muffler. Yes im pretty sure the test pipe is resonated. It not a custom test pipe. It may be Megan racing also.

Any recomendation for what brand muffler that gets rid of the rasp or should i throw another resonator on it...

 

Never heard the megan catback myself, but if it's a straightthrough design, I'll almost guarantee it's going to be raspy. You could checkout a baffled rear section, like the RSR, Magnaflow, ES Oval, or my favorite, the Apexi Noir/WS2.

 

ES tune oval are nice.

 

Apexi WS2 for life!!

Unless your going turbo.... It's 60mm or 2.36in. Great for NA, restrictive with a turbo setup.
