The AMS Alpha M5 Downpipes are the ultimate solution for improving power, throttle response and exhaust note without sacrificing quality, fitment or design. Each Alpha M5 Downpipe features a smooth transition from their massive 3.5" inlet down to the 3" tubing for optimum flow. While competitors choose a very short transition length which creates turbulence and hurts exhaust flow and power, the AMS Engineering team implemented a longer length to give your M5 maximum output.
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.
