Description

The Milltek Large Bore Downpipe with integrated Hi-Flow Sports Cat is a direct-fit turbo-back component for the VW Golf MK8 R and Audi S3 8Y. This T304L stainless steel system pairs seamlessly with OEM or Milltek cat-back exhausts, eliminating the factory restriction and unlocking dyno-proven performance gains. Engineered with a 3-inch (76.2 mm) mandrel-bent main pipe and 200 CPSI high-flow catalytic converter, the downpipe optimizes exhaust scavenging to reduce backpressure. CNC-formed construction ensures precise fitment using OEM hangers and mounting points—no modification required. T304L stainless steel construction resists thermal stress and corrosion, finished to Milltek's hand-specification standard. Fitment • VW Golf MK8 R (EA888 Gen4) • Audi S3 8Y (EA888 Gen4) • Compatible with OEM cat-back or Milltek Signature Series systems • Uses factory hangers and heat shield provisions This downpipe delivers measurable efficiency without compromise to durability or daily-driver compliance. Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
