Alpha Performance is proud to release our 100% stainless steel, tig welded downpipes for the BMW F10 M5. These pipes are available in straight through or 300 cell racing catalytic converter configuration and feature a smooth, long transition from the large 3.5” inlet to the 3” tubing for minimal turbulence and maximum performance. Designed with the latest in CAD software and laser scanned with our 3D Romer Arm you can rest assured these downpipes will fit just like the OEM parts - All O2 sensor bungs, brackets and heat shields are retained and in factory locations. With Alpha Performance downpipes installed you will notice sharper throttle response, more torque throughout the power band, reduced backpressure/spool time and an exotic exhaust note you will want to hear over and over again!
