sounds sensible mate, a rear exhaust .12 should be the way to go. not being funny, but if its a goer u might want to start a thread to gather as much info as poss - hope u can finally race it, i felt for u when u were told the funfactors werent allowed to race last time around. i think that cenracer may well be able to help u out with this.

all this winter talk and the suns out here and its about 20 degrees - ha, gonna have to take the truck out to the beach shortly i reckon.
