Description

The Milltek Large Bore 3" Downpipe with Hi-Flow Sports Catalyst is engineered for direct fitment to Milltek Cat-Back exhaust systems on Seat and VW platforms. This component pairs a mandrel-bent T304L stainless steel downpipe with a 200 CPSI high-flow sports cat to optimize exhaust scavenging and reduce backpressure.

Constructed from premium T304L stainless steel with CNC-formed flanges and TIG-welded construction. The 3" (76.2 mm) bore diameter maximizes flow while maintaining structural integrity. High-flow catalytic converter meets emissions compliance standards while delivering measurable power gains on Stage 2+ ECU tuning. Direct factory fitment uses OEM hangers—no modification required. Requires Stage 2 ECU software for optimal results.
