1st of all Fuck You. strait up. Telling me I failed. I wanted the best performing exhaust for the money. I succeded. DID I say I bough it for the looks? No. Now If I did then rip on me. They all add different amount of power. This one is by far more free flowing than my old one. Why would I not consider that in my choosing of an exhaust? Seems like you Sir are the one who buys stuff soley on looks. "They should be chosen based soley on price, sound, and looks being that horsepower is not an issue" Stop waxing your car and drive it. Your prob one of those FGT's that never even gets on it and brags about how fast your Z could go and all. STFU.
