These downpipes are properly designed and engineered using a CMM Laser Scanner for a perfect fit and space optimization. AMS took the time to integrate the factory O2 sensors, heat shielding and brackets for a clean and proper OEM-like installation. Another unique benefit is the racing catalytic converter. These 300 cell count units provide nearly no disruption in flow and feature a staked in design to hold the catalyst firmly in place.
