I seem to recall, and it was some years ago now, that when I tried to fit the exhaust made for a Tourer, it was *way* too low. I took it back and they swopped it for the correct GT exhaust. I don't know exactly what part of the system was dimensionally different to cause the problem: maybe just the length of the downpipe ............. btw the slight upward bending at the rear that I did to make it fit was for mainly cosmetic reasons.

p.s. My TA having been languishing unused in my garage for about five years has now been given to my son who has re-commisioned it and it is now back 'on the road'

Thanks for that Nigel,will post a progress report,as and when.cheers.
