Product Description

The Akrapovic S-AU/T/2H Evolution Line Titanium Cat-back Exhaust is engineered for the C8-generation Audi RS6 Avant and RS7 Sportback equipped with the 4.0L twin-turbo V8 and AWD drivetrain, including Performance and RS6 Avant GT variants. Constructed from lightweight titanium with carbon-titanium tailpipes, this system delivers a substantial reduction in exhaust weight compared to the factory system while unlocking additional horsepower and torque. Carefully tuned muffler internals and an integrated valve system give the RS6/RS7 a deeper, more aggressive exhaust note under load, yet maintain a controlled, refined character during normal driving.

Designed as a direct bolt-on upgrade that utilizes factory mounting points, the S-AU/T/2H system is optimized to work with Akrapovic's stainless-steel link pipe set and optional downpipe/link-pipe assemblies. When configured as tested, the system provides notable gains in performance and responsiveness, making it ideal for owners who demand a premium combination of sound, weight savings, and power. For C8 RS6 and RS7 drivers seeking a top-tier exhaust solution that matches the car's high-performance character, this Evolution Line titanium system represents one of the most refined and capable options available.
