I cant decide which is better: I am going with a new WB pipe and have talked to alot of people about which is better for air intake, some swear by the AF kit, or the clamp-on K&N with the dynojet kit and no air box, or the new Hot seat K&N kit witch omits just the top of the air box, any positive feedback would be greatly apreciated. My brother has the AF kit, and it definately has alot more low and mid than mine. I am also thinking on waiting for dirtwheels to do a pipe shootout, before i buy, even though most are all comparable. thanks for any info.
