vr6_super 0 Posted January 13, 2011 Report Share Posted January 13, 2011 Got my mot in March and planning putting in a ss manifold and decat str8 after on but wondering on sizes.Saw one on ebay that came with a final bore of 55mm. I heard that the standard exhaust pipe for VR6 is 2.25", however the manifold (which is specifically for VR6) comes in at 2.165"Currently I have a cat back system at 2.5" and the guy put a "sleeve" on to fit it up. If I put in manifold and keep cat, then I will have a 2.165" mani on to a 2.25" cat on to a 2.5" cat back system. Or is the standard size I heard wrong? Is it actually 2.165" ie 55mm?Obviously I am going to have to keep the car for future mots so I am better just going for a standard decat rather than the 2.5"?Help please!!!!
