i like my K&N FIPK setup. the hp gains on the dyno were as advertised and it makes a nice whistle sound at certain rpm's during acceleration thathas everyone asking what kind of supercharger i'm running.....

Yours has that whistle too?
I always assumed it was avaccum leak. Icant hear it anymore when i got my H pipe and catback. That whistle annoyed the living crap out of me, it didnt even sound cool

i have an offroad h and no cats and i can still hear it pretty good. the K&N system pulls alot of air i guess that's why. i'm getting the results i paid for so i'm happy.
