Hey guys, how would I go about toning the rasp down on the car? I have the OBX setup with a magnaflow cat with the rest of the piping stock. What should I add/remove to get rid of the horrible noise. I have dealt with it for 3 years, but it's getting old haha.

 

I took out the oem resonator and welded in a 22" magnaflow resonator a few years back. It helped to deepen the tone and get rid of some of the raspy sound your talking about.

Something else to look at are the gaskets throughout the exhaust as some might have cracks/leaks over the years. My the gasket between my axleback and pipe fell into pieces when I loosened it to check it.

 

Thank you my good sir I look into new gaskets along with a new resonator.

 

When I installed my OBX header I was not able to drive over 2500RPM without scaring other motorists with my rasp haha.

Ended up getting a larger resonator (as lanzer had said), high-flow cat and a different muffler (magnaflow #18429 I think, offhand)

 

wanna hear rasp? turbo your car and cut a 3/4" hole in your O2 housing...
