Bypass Track Pipes

On the S65 V8 M3 models, the stock exhaust headers flow very well while the catalysts present the largest obstacle and power loss. the Macht Schnell Bypass Track Pipes were designed specifically for race/track use, and offer a cost-effective means of removing the 400 cell restrictive primary catalytic converters on all 2008-2013 M3s. Bypass Track Pipes allow you to make two single cuts to your stock midpipe section, removing the catalytic converters, and clamping the largest diameter straight pipe in their place using the provided high-end/premium exhaust clamps. This eliminates the largest source of exhaust restriction, unleashing considerable power gains (~20hp) and a very obvious improvement in acceleration. Learn More
