Overview

The Milltek Large Bore Downpipe with Hi-Flow Sports Catalyst is engineered for the Audi B9 A4 2.0 Quattro Saloon and Avant. This direct-fit component optimizes exhaust flow from the turbocharged engine to the cat-back system, delivering measurable gains in horsepower and torque while maintaining emissions compliance.

Constructed from T304L stainless steel with mandrel-bent 3" (76.2 mm) piping, the downpipe features a high-flow sports catalyst rated at 200 CPSI (cells per square inch). Hand-finished construction ensures OEM+ fitment with existing Audi factory or Milltek cat-back exhaust systems. Requires Stage 2 ECU software for optimal performance mapping.
