These headers have primary and secondary lengths optimized for peak power between 6000 and 6500 rpm. The EVO - Six Dual Outlet Silencer fits behind a WEVO 915 transaxle, yet still fits inside the rear valence. It is the quietest muffler of any we have heard on a 914-6 engine, with a deep throaty tone at idle, yet never unpleasantly loud at any rpm or throttle position. The free flowing design enhances peak power compared to other mufflers when installed on any -6 header. There is NO annoying resonance at cruising rpm typical of most dual outlet mufflers. The muffler is available separately below. Minor modifications to other -6 headers (such as B&B) are required for fitment.
