Milltek Large Bore Downpipe with Hi-Flow Sports Cat | BMW E90/E92/E93 M3

Description

The Milltek Large Bore Downpipe with Hi-Flow Sports Catalyst is engineered for BMW E90/E92 M3 models and designed to pair with the Milltek Cat-Back Exhaust System. OEM catalysts restrict gas flow significantly; this hi-flow sports cat reduces that restriction, improving exhaust scavenging and supporting measurable power gains when combined with a Stage 2 ECU remap. Precision mandrel-bent T304L stainless steel construction ensures durability and consistent flow characteristics. The large bore diameter maximizes exhaust velocity. Direct factory fitment uses OEM hangers and mounting points—no modification required. Lambda wiring extension is required for installation. Fitment & Requirements: • Direct fit: BMW E90/E92 M3 (S65 engine) • Requires Stage 2 ECU remap for optimal performance • Designed for use with Milltek Cat-Back Exhaust System only • Lambda sensor wiring extension required Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
