Titanium Valved Exhaust AUDI B9 S4/S5 

Elevate your Audi’s driving experience with the PHP Titanium Valved Exhaust System, designed to bring out the true sound and performance potential of your B9-generation S4 or S5. Crafted entirely from ultra-lightweight titanium, this system not only shaves weight but also amplifies turbo response and delivers a raw, motorsport-inspired tone.

The integrated valve control allows you to toggle between a refined, quiet mode for daily driving and a more aggressive tone for spirited performance — all while maintaining factory driveability and comfort.

• Full Titanium Construction: Maximum strength with minimal weight

• Valved Technology: Switch between quiet and aggressive tones with remote or drive mode integration

• Mandrel-Bent Piping: Optimized flow for better throttle response

• Precision Welds & Finish: Built for durability and high-performance looks
