Go to a different exhaust. Unfortunately not one vendor in the worldwide Triumph vendor sphere sells a aftermarket exhaust specifically for our bikes. A made to order/fit TT style that joined into a collector beneath the front of the engine, that comes out either side and marries up with one stock configuration silencer can that connects neatly to our existing mounts? The ease of modifying our controls is severely hampered by the proximity of the headers, move them and it gets easy. I saw a Thruxton and engaged the rider at a local store, he had beautiful TT pipes, just like I described and made by Thunderbike, from NZ. Whether you're re locating foot controls or not, a choice of exhaust options, wouldn't be to much to ask for, from the entrepreneurial lot.
