I really just want it for the b18 I plan on dropping in there... Otherwise I would go with the 2 1/4.... Oh well. Hope you find out what is wrong with your exhaust! Maybe it's too free flowing? Slap a high-flow cat on there to deaden the sound a bit.

i'll probably throw a resonator on there when i get the 2" if it doesn't go away.

Okay... An update after a looooooong hibernation period. It is HOT and I finally decided to fix the air. Emptied the old freon, and loaded some new in it, but I notice when my compressor comes on it throws the idle from 900 to 2500 rpms. I suspect a vaccum leak between the compressor and the choke... Anyone else have any suggestions?
