Valvetronic Designs Valved Sport Exhaust System for B8 & B8.5 Audi S4 / S5 [AUD.B8.S4.VSES.AG.RC/AUD.B8.S4.VSES.BR.RC]

Valvetronic Designs Valved Sport Exhaust System for B8 & B8.5 Audi S4 / S5 [AUD.B8.S4.VSES.AG.RC/AUD.B8.S4.VSES.BR.RC]

Valvetronic Designs’ Valved Exhaust System for the Audi B8 / B8.5 S4 and S5 delivers a distinctive, high-pitch wail while preserving low-end rawness for a uniquely engaging sound. Built entirely from T304 stainless steel and running 2.5 inches front to rear, it features Valvetronic Designs’ high-pitch X-pipe technology to unlock an exhilarating tone across the rev range. Integrated vacuum-actuated valves controlled via the included key-fob remote—provide instant flexibility from refined cruising to an aggressive, motorsport-inspired soundtrack.

Why It Works

• Valvetronic Designs employs its High-Pitch X-Pipe technology to sharpen tone and enhance flow, pairs vacuum-actuated valve control for on-demand sound via the included key-fob remote, and uses a full mandrel-bent layout to optimize flow for quicker throttle response and stronger power delivery.

Sound & Control

• Valvetronic Designs calibrates the system for true dual personality: with the valves closed, it remains quiet for early starts and relaxed highway cruising; open the valves, and it releases the supercharged V6’s full character—deep at the low end with high-pitch excitement up top. Valve operation is handled instantly from the driver’s seat via the included key-fob remote.
