I have an 03 660 withan aluminum oil tank,air box and dual k&n's,trail tech x bars, steering stem and stabilizer, Rad raptor tapered bearing carrier, and 12 tooth front sprocket. All i really do is race and jump. I have the stock exhaust on now and as far i know the stock jetting. It's just not as fast to me now as when i first bought it. so with my income taxes i want to buy the most high performance exhaust on the market.(it needs to look good too). So any stats or specs would be greatly appreciated.
