I have an 02 raptor 660 with a stock exhaust with the baffle out of it. I'm now thinking of buying a new exhaust. i only have about 700$ available right now and i would like to put some of that into other parts so im trying to keep the price down. I wanna know what kind of exhaust you guys think is the nest for power and sound. And if it is well worth the extra cash to buy the full system not just the slip on...but im low on cash. lol Thanks in advance.
