Our SLS performance package 3 features our proprietary ECU tuning software and long tube headers as found in package 1 & 2 with the addition of the Akrapovic full titanium exhaust system for the SLS. This package combines incredible performance with substantial weight savings and creates a truly exotic sound.

The Akrapovic Evolution system for the Mercedes SLS not only produces stand alone gains of 15 hp, but reduces weight by an incredible 45 lbs over the stock system! Soundwise, the system brings out the true character of the car featuring muffler bypass valves and Akrapovic wireless kit included with the system.

Our long tube headers are designed and manufactured in house and feature high quality, tri-metal, 200 cell sport catalytic cells which are ceramic coated to reduce heat in the engine compartment as well as combat against thermal stress.

The combination of RENNtech performance and  the fierce sound of our long tube headers coupled with the Akrapovic exhaust system truly create the ultimate performance package for the SLS.
