Milltek Hi-Flow Sports Cat | Performance Catalyst
SKU: SSXMTK004
Description
The Milltek Hi-Flow Sports Catalyst is a high-flow replacement for restrictive OEM cats, engineered to reduce back-pressure and unlock performance gains across the mid-range and upper RPM band. Direct bolt-on fitment with no modification required.
Hand-finished T304L stainless steel construction with mandrel-bent internal flow paths. Reduces the density and restriction of factory catalysts by up to 40%, allowing exhaust gases to exit more freely while maintaining emissions compliance. Requires Stage 2 ECU remap for full potential.
Key specifications:
- T304L stainless steel, hand-finished construction
- Mandrel-bent internal passages for optimized flow
- Direct OEM fitment—uses factory hangers and mounting points
- Compatible with cat-back and turbo-back systems
- Stage 2 ECU remap required to maximize dyno gains
- EC approved for road use (where applicable by market)
Engineered to Exhilarate. Milltek performance catalysts unlock real dyno-proven gains without sacrificing road compliance or fitting complexity.
Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
