Description

The Milltek Large Bore Downpipe with integrated Hi-Flow Sports Cat is engineered for the VW Golf MK8 R and Audi S3 8Y (EA888 Gen 4). This system optimizes exhaust flow from the turbocharger to the cat-back, delivering dyno-proven gains in horsepower and torque while maintaining emissions compliance. Constructed from T304L stainless steel with mandrel-bent 3" (76.2 mm) piping and a 200 CPSI high-flow catalytic converter, this downpipe uses OEM mounting points and requires no vehicle modification. The design integrates seamlessly with both OEM and Milltek cat-back exhaust systems. Stage 2 ECU software tuning is required to unlock full performance potential.
