lightwave Posted November 4, 2004 Share Posted November 4, 2004 Does anyone know the size of the pipes on the various TT cars? I don't really understand what parts of the exhaust should be what size. I know 3" and 4" get bounded around. Are the sizes different for USA/UK/Jap cars when it comes to decat pipes and cat back exhausts? Thanks.

merckx Posted November 4, 2004 Share Posted November 4, 2004 If you want to get some decat pipes then get some from Chris Wilson (Do a search), these are 2 1/2" which are ideal for a TT. Also get a restrictor ring which you'll need to restict the boost from getting too high on a Jap Spec car. I got mine for £300 - decat pipes and restrictor ring Plenty of exhausts to choose from , I've got a Nur Spec R exhaust which are very popular. There's a group buy of these happening now at a very good price. Quote Link to comment Share on other sites More sharing options...
