Milltek 2.50" Non-Resonated Cat-Back Exhaust System for Audi B9 S5 3.0 V6 Turbo Coupe. Direct factory fitment replacement engineered for Sport Diff models without Brace Bars. Uses OEM hangers and mounting points - no modification required.

Constructed from T304L stainless steel with mandrel-bent tubing. Hand-finished quad GT-100 burnt titanium outlet trims. The non-resonated design eliminates the OEM resonance chamber, delivering a pronounced, full-throttle character without mid-range drone. 2.50" (63.50mm) bore diameter maximizes exhaust scavenging across the RPM band.

• T304L stainless steel mandrel-bent piping
• Quad GT-100 burnt titanium trims
