I put my KKM in about 2 weeks ago. I LOVE IT!! The sound is AWESOME, especially at anything over 4000rpm! As far as fuel economy? I haven't seen any improvement, but then again, I seem to be driving a bit "harder" lately

I did order the K&N replacement filter though. Heard too many negative things about the one that comes with the KKM kit. But i haven't had a problem yet. My advice, GO BUY IT!!
