There is a lot of power held back by the factory exhaust system on you vehicle. By eliminating the factory catalytic converters, STILLEN has successfully improved flow, creating power gains as well as dramatically improving sound. Catalytic converters are not only very restrictive to the exhaust flow and performance, but they also act as mufflers, greatly reducing the sound that enthusiasts desire. The all new STILLEN Y-pipe is constructed of 304 stainless steel and mandrel bent for smooth flow of gasses without restriction.
