Product Description

The **Akrapovic S-AU/T/3H** is a high-performance, full titanium *Evolution Race Line* exhaust system designed specifically for the 2025 **Audi RS Q8 (4M)**. Built with ultra-light titanium for both the muffler and valves, this system dramatically reduces weight while improving exhaust flow and sound.

With dual electronic valves and an X-connection link-pipe (CO-AU/T/5 required), the S-AU/T/3H provides a distinct sonic character: a sharp, high-pitch race tone at high RPMs, and a deep, authoritative V8 growl in low revs. A "comfort" mode further dampens noise for refined daily driving without cabin drone.

Installation is plug-and-play when used with Akrapovic's titanium link-pipe set. This setup is certified with ECE approval (on OPF/GPF-equipped RS Q8), meaning no ECU tuning is required, and it delivers verified power and torque gains while maintaining regulatory compliance.
