🏁 AUDI RS5 B9 VALVED SPORT EXHAUST SYSTEM | PISTON TWISTIN

The Audi RS5 B9 packs serious twin-turbo power, but its stock exhaust keeps that performance far too quiet. The Valvetronic Designs Full Valved Sport Exhaust System unleashes the RS5’s true sound — an aggressive, motorsport-inspired tone when open, and quiet refinement when closed.

Built as a complete T304 stainless steel system, this setup eliminates the need to mix components from multiple brands. It’s a one-and-done performance upgrade engineered for precision fitment, maximum flow, and OEM-level valve control.

⚙️ WHY IT WORKS

• Full-System Design: Replaces the entire exhaust path — no need to combine mid-sections, resonators, or cat-backs from different manufacturers.

• Electronic Valve Control: Instantly toggle between track-ready aggression and subtle, daily-drivable refinement.

• Optimized Flow Path: Mandrel-bent construction minimizes restriction and enhances turbo response across the rev range.

• Lightweight Upgrade: Sheds 16.3 lbs versus the factory exhaust, improving throttle response and overall balance.

🔊 SOUND & CONTROL

• Valves Open: Bold, commanding tone with defined overrun crackles and sharper turbo note.

• Valves Closed: Quiet, composed sound for highway cruising or residential areas.
