Really? Are there pictyures of this car? I'd like to know more, especially if its owner has created his own exhausts, or modified them, what experience he has? I have clocked during these 3 troubled years of ownership only about 12.000 kms with my own, and I consider myself a long distance runner (as anyone that knows my posting history knows), but so far no exhaust set has lasted more than consecutive 3.000 kms without cracking (and some a lot less), so any dream of attending a M3W Jungfrau-Treffen (and back) is squashed by previous experience and reasoned thought.
If the owner of that Brooklands isn't a TMer I won't be able to contact him, but in any case if there are pictures of that car's exhausts I'd be very interested in viewing them!
