Description
The Milltek Cat Back Large Bore Downpipe with Hi-Flow Sports Cat is a precision-engineered turbo-back component designed to optimize exhaust flow and reduce backpressure across a wide range of performance vehicles. This system pairs a 6.0" mandrel-bent T304L stainless steel downpipe with a high-flow catalytic converter (200 CPSI) to deliver measurable horsepower and torque gains while maintaining emissions compliance.

The hi-flow sports catalyst maintains environmental standards while maximizing scavenging efficiency, ideal for Stage 2+ ECU tuning. No modifications required for factory hanger fitment.
