anyone know what the storys is with the exhausts fitting. when I go on to websites looking at buying one it just says from 01 up.. another place was 01-07 so I'm thinking it might fit then I was told there not the same.. I dunnno
After market exhaust systems on the newage cars are normally sold in three sections. Down-pipe centre section and back-box. If you are going for a full system I would recommend a 3" system with sports cat or fully de-catted. You will have to note the flange type required for the turbo. AFAIK there are two types standard and twin-scroll (JDM)
If you are going to only buy a section e.g. back box, just make sure the flange is the same size as your own
A couple of the traders on the site will be able to help you in more detail if required
