Audi B8 / B8.5 S4 & S5 Valved Exhaust System

T304 Stainless Steel, High-Pitch X-Pipe, Vacuum Valve Control

Overview

Transform your supercharged V6 into a true auditory experience.
Our Valvetronic Designs Valved Exhaust System for the Audi B8 and B8.5 S4/S5 delivers a unique, high-pitch wail while retaining low-end rawness for a sound profile unlike anything the platform has heard before.

Constructed entirely from T304 stainless steel and featuring our high-pitch X-pipe technology, this system runs 2.5 inches from front to rear, unlocking an exhilarating tone across the entire rev range. With integrated vacuum-actuated valves controlled via an included key fob remote, you have instant flexibility to switch from refined cruising to an aggressive, motorsport-inspired soundtrack.

Why It Works

  • High-Pitch X-Pipe Technology: Creates a sharper, more exotic tone while enhancing flow.

  • Vacuum Valve Control: Allows on-demand sound control from the included key fob remote.

  • Full Mandrel-Bent Design: Optimized flow for improved throttle response and power delivery.

Sound & Control

  • Valves Closed: Quiet enough for early morning starts and comfortable highway cruising.

  • Valves Open: Releases the full character of the supercharged V6 with both low-end depth and high-pitch excitement.

  • Remote Control: Operate valves instantly from the driver’s seat using the included key fob system.

Construction & Options

  • Material: T304 stainless steel for long-term durability and corrosion resistance.

  • Weight Savings: 12.3 lb lighter than the factory exhaust.

  • Craftsmanship: Precision TIG welds and mandrel bends for maximum flow and strength.

  • Diameter: 2.5" tubing from front to tips.

Fitment

  • 2010–2016 Audi S4 (B8/B8.5)

  • 2010–2016 Audi S5 (B8/B8.5)
