This downpipe is the pure key to turning your MS3 into a real beast. The stock MS3 made 274 ft-lbs and 244.1 whp on TurboXS's in-house Dynapack Dyno. Adding the MS3 Downpipe and the MS3 Racepipe, TurboXS saw an average peak torque gain of 50 ft-lbs and a peak wheel horsepower gain of 40 whp. Without a doubt, reducing the restrictions after the turbocharger is the best way to achieve huge torque and massive horsepower gains. The downpipe's bellmouth is made from investment cast stainless steel and was engineered with clearance notches to ease installation. The bellmouth was used to give your wastegate the proper flow characteristics to avoid a boost creep and promote high exhaust gas velocity. 3 inch diameter mandrel bent stainless steel is used throughout to Downpipe to compliment the bellmouth housing and a cast stainless steel flange completes the downpipe. The MS3-DP is designed to mate to the TurboXS catless race pipe (MS3-RP). To reduce the risk of throwing a Check Engine Light (CEL) due to removing the factory catalytic converter, TurboXS has extended the bung for the rear oxygen sensor.
