Right, recently i fitted a scorpion cat back. all sweet and easy. except i never thought about how im going to attatch a 3inch bore pipe to a standard i think (2.25). i have used the standard sleeve and stretched one end to fit over the scorpion but its a bodge, blows, and even with some gun gum it sounds like a tank. I NEED HELP LOL. have looked on ebay, called local garags, even long life exhaust and they cant help. ??
