Ok, i ordered the Airmass exhaust off ebay for 168.95 shipped. Good quality, nice sound...but the mid-pipe is about a 3/4-inch too short. My catalytic converter is shot...and i was wondering if there was another cat converter i could swap in and take up the slack. I have a 92 Civic LX...is one of the integras any longer by chance or the EK? I do know for a fact that this would clear up my poor gas mileage, my rattles, and my fitment issues. Thanks guys
