Description

Audi RSQ8 Valved Cat-Back Exhaust System

T304 Stainless Steel with OEM-Style Electronic Valve Control

Overview

The Audi RSQ8 blends supercar performance with SUV practicality—but like many modern performance vehicles, its factory exhaust keeps things a little too restrained. The Valvetronic Designs Valved Cat-Back Exhaust System unleashes the full potential of the 4.0L twin-turbo V8, giving it the voice it deserves.

This 3-inch system runs from the downpipes to the OEM exhaust tips, offering two distinct personalities: valves closed for refined, factory-like cruising, or valves open for an unfiltered, aggressive soundtrack. For those who want even more performance and volume, our optional free-flow downpipes take things to the next level.

Controlled via OEM-style electronic valves, the system offers long-term reliability, seamless integration, and unmatched flexibility.

Why It Works

  • 3-Inch Diameter Tubing: Maximizes flow for improved throttle response and power.

  • Dual Sound Modes: Quiet refinement with valves closed, motorsport aggression with valves open.

Sound & Control

  • Valves Closed: Stock-like sound levels for comfortable daily driving and highway cruising.

  • Valves Open: Silencer fully bypassed for maximum volume and character.

  • Optional Free-Flow Downpipes: Unlock even more performance and an enhanced exhaust tone.

Construction & Quality

  • Material: Signature T304 stainless steel for strength and corrosion resistance.

  • Weight Savings: 11.5 lb lighter than the factory exhaust.

  • Craftsmanship: Precision TIG welds for durability and premium finish.

  • Tips: Designed to retain OEM exhaust tips for a factory-fit appearance.
