Greddy exhaust question.
 

Does greddy exhaust really give you 21hp bc thats what greddy claims but i just cant beleave it. if anyone have it how is the sound too im thinking about buying it.

No, the Greddy SP2 exhaust gives 2-4hp. I'd assume the claim for 21 is for the Greddy SP2 and a midpipe together, but even then that is still roughly double what you can expect.

Yeah, Greddy is not exactly the most honest company. They probably missed an decimal point in their. Closer to 2.1 hp than 21 hp.

Greddy give loud exhaust with a midpipe and dumb ass neighbors who get mad at u because they think u are going fast lol
