 This complete exhaust system consists of a high quality, lightweight titanium outer shell and muffler end cap with stainless steel link pipe and elbows. The exhaust system  weighs 3.0 kg less than the stock system. Since the complete system is delivered without Katalysator and was only developed for use on racetracks or closed courses, a DB killer is included in the scope of delivery. Designed to blend into the lines of the motorcycle , the front silencer is located under the bodywork, hidden by the lower fairings, and the rear silencer steps on the right-hand side des motorcycles off. It features a distinctive heat shield inspired by those on the Yamaha R6 and R1. The racing sound matches the bike's sporty aspirations.
 An optional black coated aluminum muffler bracket is available for the R7 without passenger footpegs.
