The exhaust I have is for a GC8, but I have a 2.0 Turbo. They are slightly different. The GC8 exhaust is slightly longer, and the flanges are a different angle. People usually cut the flanges and turn them around and reweld them. Being that I don't have a welder, nor know anybody who will weld stainless steel, I'm going to cut the flanges off the centre pipe and the back box, and just use a sleeve adapter to fit them together since they are both 2.5" in diameter.
