Valvetronic Valved Sport Catback Exhaust System - Audi RS Q8 2020-2025
Lease for as low as $/week
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.
-

-
OEM Valve Integration: Maintains factory electronics for trouble-free operation.
Sound & Control
-
Valves Closed: Stock-like sound levels for comfortable daily driving and highway cruising.
