Ok I just finished putting some EBAY headers (don't know what the hell they are, don't flame for $60 NEW there were worth it), Helix test pipes, Top Speed Y-Pipe. Total cost was under $200 easy.

I already had the Nismo intake on there. So here is the problem: I left the stock B-pipe and muffler on there because I liked the stock sound, well it sounds competely different now. Nowhere near the same. I have a rattle under at the y-pipe and test pipe connection and it is RASPY as hell. Loud, much faster but inside the car sounds raspy. Now I hear people say the same thing and outside the car it sounds a lot better, is that my case?

What can I do besides change to resonated test pipes? Change the b pipe to a straight through one? Change the muffler to straight pipes or aftermarket topspeed exhaust?

Thanks for the help guys.

 

the raspiness will increase as the flow path opens up.

from what i understand topspeed is a pretty loud exhaust, highly unlikely it will help out the situation.

trouble shoot the rattle(should be an easy fix)
to fix rasp get resonated test pipes or add resonaters further down the exhaust path(worked for me on my last car)

 

You can replace the test pipes with resonated test pipes. You can scrub the entire exhaust and get a cat-back exhaust system. Any alteration will alter the sound. But chasing some elusive exotic sound will get very expensive.

 

I have a greddy sp2 muffler for sale that would work. Asking $200.00 plus shippng.
