Renntech is known to maximize performance out of every Mercedes-Benz model imaginable, and this time they’ve taken their talents to the SLS AMG supercar. Their new long tube headers adds 20-hp and 20 lb-ft of torque to the factory 563-hp and 480 lb-ft values. These long tube headers were engineered within Renntech’s state-of-the-art facility and features tri-metal, 200-cell catalytic converters and are ceramic coated to reduce heat in the engine bay.

In addition to the horsepower and torque gains, the SLS AMG gains a much throatier note from its naturally aspirated 6.2L V8 powerplant. The result is a finely tuned addition to the SLS AMG’s already remarkable performance and with Renntech’s brand name behind the product it’s guaranteed to last.

Check out a video of Renntech’s SLS AMG after the break.
