I'm running without the exhaust fan also, but i have an reversible intake/exhaust fan in my console, mines an 07 and the mid pipe to head pipe is also rotten, ordered the Muzzy's, can't wait til they get here, where are you in canada? you can have my stock system with custom raptor tip for free 2, i'll send it C.O.D.....probably still seal up better than a new gibson
if your gonna buy new, go with the muzzys or R.W. otherwise your wasting your money.
