I just swapped a d16y8 SOHC VTEC into my 88-91 Civic hatch. I have a Tenzo R axle back exhaust and it sounded great when I had the old motor (which had a cat converter). The new motor has a DC header on it and no cat so it is screamin' loud! And this isnt a good loud, this is like a shit kicking cherry bomb glass pack loud. I am pretty sure I just need a cat converter. Should I get a plain one or one of the high flow cats you see on ebay or what? Thanks a million!
