^ Yea I rememeber that ****, I was at your house, I think when I bought your old steering wheel, you reved your old coupe up man it was LOUD and that was without a header....I still think it was louder then my Blitz exhaust lol, it made a HUGE difference with the resonator......Megan racing, Project Nissan sells a resonator that replaces the Cat, the MEgan Racing header comes with the resonator already, Jspec.com sells it for $240, only bad thing about it is the 4-1 design i like the hotshot 4-2-1 design better, OOPS sorry gettting off topic. if you want it quiet go with the rsr EXMAG, IMO quietest on the market besides Stock, its 3inch but on a comple forums I have seen dynos where KA's made nice gains using 3inch exhausts.
