The bores are different but if its coming straight off the downpipe it should fit i was running a vr6 exhaust much bigger bore with de cat and middle box removed with no problems. that was on my 8v some people will say no some will say yes i know it will from the downpipe so long as you have the flange type which either turns or is solid cant remember which way round. If your after a system i have a decated magnex stainless steel system for the 8v all welded solid no blowing apart from abit of mid box rattle nothing serious straight fit twin exit about 2" double pipe back box?
