The Alpha M5/M6 Downpipes are the ultimate solution for improving power, throttle response and exhaust note without sacrificing quality, fitment or design. If you are looking for the highest quality downpipes for your new M5/M6 look no further!

Computer Aided Design Yields Maximum Results

Each Alpha M5/M6 Downpipe features a smooth transition from their massive 3.5” inlet down to the 3” tubing for optimum flow. While our competitors choose a very short transition length which creates turbulence and hurts exhaust flow and power, our Engineering team implemented a longer length to give your M5/M6 maximum output.

Unparalleled Fitment Through Proper Engineering

The Alpha M5/M6 downpipes aren’t something we quickly whipped up in a fabrication shop. These are properly designed and engineered using a CMM Laser Scanner for a perfect fit and space optimization. We took the time to integrate the factory O2 sensors, heat shielding and brackets for a clean and proper OEM-like installation. When you chose Alpha there is no need to hack up your prized possession.

An Exhaust Note That Is A Real Head Turner

These upgraded downpipes keep the exhaust note mellow at cruising speeds for driver and passenger comfort but offers a deep rumble when you lean into the throttle. The end result is a perfect balanced sound for the ultimate performance sedan!

The Difference Is In The Details

Another unique benefit is our motorsports catalytic converter option. These GESI brand 300 cell count Ultra High Output (UHO) units provide virtually no disruption in flow providing emissions control with no notable loss in horsepower. For durability these converters feature a staked in design to hold the catalyst cores firmly in place. Many competitors offer a low quality converter option to keep the cost low and profits high. Often, these units fail due to poor construction and inferior materials. When you choose Alpha Performance, you will remain worry-free for years to come.
