Notes:

The 2500M uses the earlier TR6 double downpipe.

I have not listed all the other parts as they are 'TVR Specific' (well, as car specific as any muffler system can get!). The exhaust parts are probably available from David Gerald, or Gene Bird at some rediculous price....I suggest you purchase the header and downpipe from any british car specialist (Moss etc.) then print out the above picture to show to the local muffler shop who can match the parts for a lot less money. Personally, I am not an originality freak, so I am going to have the local muffler shop put on a dual system with glasspacks rather than join up both pipes as stock. They'll exit the rear of the car as stock though.
