Our Evolution performance exhaust system, made of our proprietary titanium, includes a muffler, link pipes, and resonators that run from the stock down pipes back. These link pipes feature larger-than-stock-diameter tubing and cast titanium flanges. The secondary catalytic convertors are removed, further decreasing back pressure and weight while at the same time deepening the exhaust tone and increasing power output. For the ultimate in weight reduction, tuning potential, and aggressive racing sound, we offer optional stainless steel catless down pipes. For hardcore enthusiasts. Select the optional Akrapovic sound kit for adjustable sound. Complete the look with a set of four exquisite tailpipes in titanium or carbon fibre.
