Restrictions in the exhaust system rob horsepower and torque, especially on turbocharged cars. Thus, removing exhaust flow restrictions will increase horsepower and torque significantly. The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction. Evolution Racewerks' Sports Series 4.5" High Flow Catted Downpipe is the perfect solution to improve your BMW's power capabilities! Featuring a high-flow 200-cell metallic catalytic converter and 4.5"/4" mandrel-bent piping, this downpipe is designed to provide the highest exhaust flow possible without triggering a Check Engine Light. Additionally, this downpipe can be used with your stock or aftermarket* exhaust systems, eliminating the need to have a muffler shop adapt this downpipe to your existing exhaust system.
