This exhaust was CAD designed to fit the Buell XB series motorcycles. This is the best fitting and performing race exhaust in the world for the Buell XB. Included in the photos is a image of the exhaust fitted to the bike when it was new and being fitted before it was ceramic coated. The chips or scratches on the pipe is in the ceramic coating which under race conditions which were easy scratched. If the pipe was ceramic coated again is would look like new. This pipe cost $2900 to build without the R&D costs. The muffler can be removed and repacked if necessary. This exhaust does not provide ports or bungs for oxygen sensors but they can be installed. I will include an exhaust bracket for the muffler that is not pictured. The muffler tail pipe is specially designed to NOT blow exhaust on your right foot or the swingarm( heating up the oil )
The exhaust has produced 125 Horsepower at the rear wheel on our 1170cc race engines with a modified 49mm single throttle body. On our 1426 cc full race engine with 51mm throttle body we have produced 138 Hp at the rear wheel and on our dual 49 mm throttle body 1426 cc race engine we have made 149 horsepower at the rear wheel.
The exhaust is made out of stainless steel and has a nice throaty sound. It can be installed on a stock bike and if run on the proper race gas and tuned correctly we have made over 100 Hp at the rear wheel of a stock XB12.
