Description
Milltek 2.50" 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 (2016+ S4 sedan/Avant, 2017+ S5 Sportback). Quad GT-100 polished tips. T304L stainless steel construction, mandrel-bent throughout.
The resonated design delivers an engineered tone that enhances the OE+ character while maintaining composure at cruise. 2.50" (63.50mm) diameter pipe optimizes exhaust scavenging for the 3.0 turbo's airflow requirements. Hand-finished welds and CNC-formed flanges ensure OEM-quality fitment. Uses factory hangers and mounting points-no modification required.
Fitment
- Audi S4 B9 3.0 V6 Turbo - Saloon and Avant (sport differential, no brace bars) - 2016+
- Audi S5 B9 Sportback 3.0 V6 Turbo (sport differential, no brace bars) - 2017+
Resonated cat-back systems preserve rear valence fitment and maintain OE compatibility. T304L stainless steel resists thermal cycling and road salt for proven longevity.
Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
