When it comes to the S55 engine, removing the factory limitations offers a plethora of power. Additionally with turbocharged vehicles, unnecessary resistance and pressure can constrict the efficiency of airflow. By introducing catless downpipes, the exhaust system is relieved of back pressure that suppresses the turbos ability to spool air. With that increased airflow, catless downpipes offer a serious power upgrade. 

With Speed Logic’s Upgraded Downpipes, an additional 20-25 horsepower and 25-30 lbs torque to the wheel can easily be added with this simple upgrade. These numbers have been track proven and tested in order to validate their gains. In addition to the supplemental power, we only provide the best of materials and construction allowing us to offer a lifetime warranty from defects. Installation hardware and components will be included with a purchase along with our satisfaction guarantee.

LIFETIME warranty is included with all Speed Logic Downpipes.
