Remus does one and I believe Wolf racing does as well. However the Yoshimura is the best, producing more hp than the Sebring - which was the pipe sold as the official Triumph race pipe. The Sebring sounds good, especially when the packing is out but does not improve the mid range - the Yosh produces better mid range and torque and has a roart that at high rpm is gorgeous. If you find some pictures of the original Speed triple challenge series and look at the header designs of the bikes you'll see that most are not of the Sebring variant. TTS of Nottingham, in the UK designed the header which became the Yosh pipe - finding the early expertise is going to be difficult but header design is important. The Sebring is a double Y affair, the #1 cylinder pipe goes straight to the collector, and the # 2 & 3 join quite close to the exhaust ports - supposedly for better top end. The Yoshimura however is a variant of the stock pipe, with out the crossover and one collector - the # 2 pipe joins the #1 pipe mid way down before the curve and #3 pipe meets it just before the collector. There is a weld bead on the Sebring at the entry point from the exhaust port, which is restrictive but has a Triumph decal plate on the can. The Yosh has no bead and therefore less restrictive. Check Hinckley's album page for picture of the Remus, he has his on the Super 111- the Wolf I know nothing about but would want to see the header to get an opinion. The Sebring and Yosh you'll only find used - new the Sebring was $900, the Yosh -under $500 -mmmm! Goes to show, you don't get what you pay for. :razz:
