sharky_70 0 Posted February 22, 2010 Report Share Posted February 22, 2010 say i was to buy a 3" downpipe with the 3 bolt flange, would that match pretty much straight up to a 2.5" cat/exhaust with the same flange? i know there will be a step down in dia. but will the flanges be the same size?

legvw 0 Posted February 22, 2010 Report Share Posted February 22, 2010 It depends where you buy it from and if its been made to fit the original flange. If your have it made buy a 3 bolt gasket for it to be matched to that, then it should fit. Link to post Share on other sites
sharky_70 0 Posted February 22, 2010 Author Report Share Posted February 22, 2010 well i assume that it was deisgned to fit stock d/p flange, and the d/p im looking at should work with the stock cat. so im guessing yes?! Link to post Share on other sites
