Overview

High-flow primary downpipe with integrated sports catalyst and turbo elbow, engineered to reduce backpressure and improve turbo spool response. The lower-density sports catalyst allows exhaust gases to flow more effectively than OEM, while the wide-diameter turbo outlet accelerates boost delivery and throttle response. Direct OEM fitment; compatible with both Milltek and OE cat-back systems.

Technical Specification:

  • T304L stainless steel construction, mandrel-bent primary pipe
  • Hi-Flow sports catalyst with low restriction core

  • Stage 2+ ECU remap required for full calibration
  • OEM hangers and fitment points preserved

Milltek downpipes are engineered for forced-induction platforms where boost response and mid-range spool are critical. This system pairs seamlessly with Milltek cat-back configurations or factory rear sections, making it an ideal foundation for incremental turbo upgrades.
