CTS TURBO MINI F54/F55/F56 COOPER S | BMW F48 X1/X2 B46 DOWNPIPE

CTS Turbo's downpipe for MINI Cooper S (F54/F55/F56) and BMW F48 X1/X2 models equipped with the B46 engine addresses the restrictive factory exhaust system. This precision-engineered replacement bolts directly in place of the original catalytic converter section, opening up the exhaust path where the factory component creates significant backpressure. Built for tuning workshops preparing turbocharged B46 powerplants, it supports enhanced breathing required when calibration and hardware modifications push beyond standard outputs. Essential groundwork for builds targeting meaningful performance gains through the exhaust system.
