Audi S5 3.0 TFSI (B8/8.5) Coupe Cat Back Performance Exhaust

Audi S5 B8 and B8.5 3.0 TFSI Coupe stainless sports system for sharper response, richer tone and premium finish. If you are chasing an upgraded soundtrack, freer breathing and a high quality rear section upgrade for your V6, this UK built system delivers.

Designed specifically for the Coupe body, this rearward-from-catalyst upgrade replaces the mid and back sections with larger bore, mandrel bent T304 stainless tubing for smoother gas flow and long term durability. It is a direct fit, expertly engineered by Cobra Sport, and supplied with the required hardware and gaskets.

• Fitment: Audi S5 3.0 TFSI V6 petrol, B8 and B8.5 generation, Coupe only
• Configuration: runs from the catalyst rearwards - replaces centre section and rear silencer assemblies
• Tubing: 2.5 inch 63.5 mm T304 stainless, mandrel bent for consistent internal diameter
• Options:
  • Resonated - includes centre silencer for a refined, sporty tone on daily use
  • Non-resonated - removes the mid silencer for a louder, more aggressive note
• Tailpipe styles: quad outlet to suit the factory diffuser - choose 3.5 inch twin slash cut angled tips or 3.5 inch twin inverted slash cut angled tips
• Dyno proven: recorded gains of approximately +7.3 bhp and +8.2 lb ft on rolling road testing
• Sound testing: quieter than stock at idle by around 1 dB, with the non resonated version measuring approximately 67.2 dB at 4,000 rpm, an increase of about 15.7 dB over OE
• System mass: approximately 32.14 kg with upgraded resonator and rear box
• Includes: all relevant fittings and gaskets for installation
