Description

Milltek 2.50" Non-Resonated Cat-Back Exhaust System for Audi B9 S4 and S5 3.0 V6 Turbo. Direct factory fitment for Sport Differential models without brace bars. Hand-finished T304L stainless steel with quad GT-100 polished tips. Mandrel-bent construction engineered for maximum exhaust flow and aggressive sound character. Constructed entirely from T304L stainless steel with CNC-formed GT-100 polished triple-wall tips. Uses OEM hangers and mounting points-no modification required. Non-resonated design eliminates mid-range drone points for a full-throttle tone without cabin resonance at cruise. Dyno-proven gains in mid-range torque across the 3.0 V6 Turbo EA839 engine platform. Fitment • Audi S4 B9 Sedan/Avant (2016+) - Sport Diff models only, without brace bars • Audi S5 B9 Sportback (2017+) - Sport Diff models only, without brace bars Every system is hand-finished, tested for fitment and acoustic signature, and manufactured to OEM+ standards. This non-resonated cat-back delivers the engineered tone character that separates precision stainless fabrication from off-the-shelf alternatives. Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
