RENNtech Package 2 (SLS- 626 HP / 530 TQ)

The SLS performance package 2 features our proprietary ECU tuning software and long tube headers as found in package 1 with the addition of our sound and performance x-pipe exhaust. This combination unleashes the beast lurking underneath the refined exterior of your SLS. The 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. Our sound and performance x-pipe is constructed of high quality stainless steel and features a secondary catalytic bypass with power proven x-pipe crossover design allowing for free flowing exhaust with less backpressure and greater performance.
