What is the closest-to-stock muffler that I can put on my 4th gen without modification? I have a wpspd y and b pipe. What muffler will bolt up to the car without adding much noise, if any? Thanks!

$10 says you could get a insanely great deal on a stock muffler if you post a WTB, since most of us have aftermarket ones. The only quiet one is the HKS, but I've heard that it actually decreases performance. Better off with stock.

 

5gen stock, 4th gen stock.. paint the resonator black.. remove the stock tip, saw off the nasty real exhaust opening and add a 3 tip...i think that will be nice..

i think the new 350z has a stock 3 inch tip.. try and get one from someone ona z org.
