Unlock the true performance and sound character of your Audi TTRS MK3 with the Valvetronic Valved Sport Exhaust System—a premium upgrade engineered to enhance exhaust flow, sharpen throttle response, and deliver an exhilarating exhaust note on demand. While the 2.5L 5-cylinder engine is celebrated for its iconic tone, the restrictive OEM cat-back system limits both volume and emotion. Valvetronic’s high-flow valved system corrects this with a 3-inch stainless steel exhaust that brings out the raw personality of the legendary 5-cylinder engine.

The system increases piping diameter to a full 3 inches, significantly improving exhaust gas velocity and engine responsiveness. At the core of the design is the rear Y-section. With the valves open, exhaust gases flow straight through to the large polished tips, producing an aggressive, high-output sound ideal for spirited driving. With the valves closed, gases are routed through a quad-chambered center muffler designed to reduce volume while maintaining smooth tone quality—perfect for neighborhood driving, highway comfort, and daily use.

Constructed entirely from premium T304 stainless steel, the exhaust is fully mandrel-bent for unrestricted flow and precision TIG-welded for long-term durability. The system retains seamless compatibility with the OEM electronic valve motors, ensuring full use of factory valve functionality. Additionally, the exhaust reduces total system weight by 14.8 lbs, improving vehicle dynamics and responsiveness. With a fully reversible design, the system installs without permanent modifications and can be returned to stock at any time.

Whether you're daily commuting or pushing the TTRS on back roads or track days, the Valvetronic Valved Sport Exhaust System delivers the ultimate balance of sound, performance, and refined engineering.
