RENNtech Package 1 (SLS- 608 HP / 519 TQ)
Description
The SLS performance package 1 features our proprietary ECU tuning software combined with our long tube headers unbelievable sound with performance to match.
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. The long primary tube headers generate incredible low end torque for quicker acceleration of the line and improved exhaust gas flow with reduced backpressure. This coupled with our ECU tuning software ensures the bite of your SLS is as wicked as the bark of the exhaust note.
