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.

Power gains for the SLS with both the ECU upgrade as well as performance exhaust (secondary cat bypass and x-pipe) are as follows:

+40 hp and +40 lb/ft @ crank

 

Please remake Jay Leno's driving video with this car. Damn that thing sounds amazing!

 

big gains. BTW the sls is so much better looking that the SLR its amazing. It really is a lot more car for half the money. No video at work so I can hear this beast.
