Take your Audi B9 S4 or S5 to the next level with the STRATEC Ultra-Light Titanium Valved Exhaust System , engineered for maximum weight reduction, performance, and sound control. Built for enthusiasts who demand the lightest possible setup without compromising durability, this system delivers a sharp, aggressive exhaust note when valves are open and refined, OEM-like behavior when closed.
Designed as a complete one-piece system from the downpipe connection to the exhaust tips, this exhaust eliminates the need to mix components from different suppliers, ensuring consistent sound quality, perfect fitment, and seamless performance.
With valves open, expect a crisp, motorsport-inspired tone with pronounced overrun crackles. With valves closed, the system remains quiet and comfortable for daily driving—without drone when paired with the factory downpipe.
Why It Works
Ultra-Light Titanium Construction: Significant weight savings over stainless steel
Electronic Valve Control: Instantly switch between aggressive and refined sound
One-Piece System Design: No need to mix axle-backs or resonators
Mandrel-Bent Titanium Tubing: Maximizes flow and throttle response
Sound & Control
Valves Open: Loud, sharp, and performance-focused exhaust tone
Valves Closed: Quiet, refined, and daily-drivable
No Drone: When paired with the OEM downpipe
Construction & Details
