For more than 21 years, RENNtech has been a foremost authority on Mercedes-Benz tuning and offering a complete line of performance products for Mercedes-Benz, AMG and Maybach vehicles. Their latest offering is for the Mercedes-Benz SLS AMG and gives the already speedy SLS and extra 20 HP and 20 LB Foot of Torque.
Designed and engineered in house specifically for the Mercedes SLS, RENNtech’s long tube headers feature high quality, tri-metal, 200 cell sport catalytic cells and are ceramic coated to reduce heat in the engine compartment as well as combat against thermal stress.
The long primary tube design allows for improved low end torque resulting in improved off the line and bottom end performance. The reduction in exhaust system back pressure and free flowing design also dramatically improves overall performance with a head turning exhaust note for a bark as wicked as its bite.
