I previously bought a aem v2 for my 93 civic ex sedan but after i bought it my z6 crapped out on me so i am building a b16 to put in it. I was wondering if the piping size was the same on the v2 for the z6 and the v2 for the b16 or if the piping is bigger on the b16 v2? any help is apreciated... thanks...
