The Alpha Mercedes-Benz M133 AMG Cast Downpipes are the best performing and most durable on the market! During testing our shop CLA with our Alpha M133 2.0L AMG Downpipe, Filter, and Alpha M133 Tune our Engine Calibrators saw amazing gains across the power band in both wheel horsepower and torque! The power came on earlier and carried over 100 ft lbs of torque gains from 2900rpm to 4850rpm!!! Turbo spool-up was significantly improved! The long gradual transitions within the cast down pipe section allows exhaust gasses to maintain velocity without a buildup of back pressure inside of the system!
