Thanks Dickybeau, her in doors got me a custom made back box for xmas so I'm after the manifold and downpipe. Your not the first to say that the manifold did not fit, so I'll probably get the guy from powerflow in Leek to give me a quote, I think it might be a little more than toyosport but at least if it goes wrong I've only got a 15 minute drive to get it sorted.
I was going to get Powerflow to look at my TF and quote for a custom exhaust, but a friend at work told me he knew a few people who had had some issues with bad fitting exhausts from there. In the end I bought a TT Mk.7 from MGFnTFbitz and a new stainless downpipe and I am really happy with the price and the quality of the parts!
The TT looks great and sounds superb!
I was also recommended JP exhausts in Macclesfield, but when I spoke to the, they could only fabricate a custom backbox.
If you do get a custom exhaust made, just make sure the finishing pipes are central and have enough clearance around the pipe, or you could get a warped or melted rear bumper.
