RENNtech is proud to introduce our performance exhaust system featuring secondary catalytic bypass pipes and rear x-pipe for the new Mercedes SLS AMG. Our exhaust produces an intoxicating growl at idle and incredible exhaust note under load. In conjunction with our proprietary ECU tuning software, our exhaust unleashes the beast lurking underneath the SLS's refined exterior. Here is the video. Enjoy.
