Audi B9 RS5 Valved Exhaust System

Full T304 Stainless Steel System with Electronic Valve Control

Overview

The Audi B9 RS5’s 2.9L twin-turbo V6 is a powerhouse—but the factory exhaust hides much of its true character behind heavy, restrictive components. The Valvetronic Designs Full Valved Exhaust System unleashes the car’s full vocal potential, delivering an aggressive, motorsport-inspired tone when desired, and quiet refinement when needed.

Unlike typical aftermarket setups requiring multiple parts from different vendors, our system is a complete, single-package solution—from the OEM or aftermarket downpipes all the way to the exhaust tips. No more combining a cat-back from one brand with resonator sections from another—this is a true one-stop upgrade.

With the valves open, the RS5 gains a sharper tone, aggressive overrun crackles, and a commanding presence. Close the valves, and the car returns to near-stock quietness, making it ideal for both spirited driving and daily use.

Why It Works

• Full-System Design: Replaces the need for mixing exhaust components from different brands.

• Electronic Valve Control: Instantly switch between aggressive and refined exhaust modes.
