Velocity Exhausts Porsche 991 Turbo S Exhaust System

Porsche 991 Turbo S Exhaust System

Built for the twin-turbo flat-six that made the 991 Turbo S a benchmark for all-weather supercar performance, this exhaust system is engineered to unlock the aggression the factory setup was tuned to hide. Whether you want a subtle daily upgrade or a full race-inspired soundtrack, this system delivers sharper throttle response and a tone that finally matches the car's output.

Fitment

Sound Character

The 991 Turbo S's flat-six is capable of a much deeper, more mechanical voice than the factory system allows — this system lets it out.

• X Pipe / Race X Pipe Design: Improves exhaust scavenging across both turbos, sharpening throttle response and producing a deeper, more resonant tone than the factory setup.
• Overrun Character: Aggressive pops, crackles, and turbo burble on deceleration and downshifts, most pronounced on the Race X Pipe non-valved configuration.
• Overall Profile: Deep and mechanical at idle, opening into a sharp, forceful pull through the rev range — from a refined daily tone (valved) to an unapologetic race note (non-valved).

Materials & Engineering

• Available in Brushed T304 stainless steel or aerospace-grade Grade 5 titanium for maximum strength-to-weight ratio

• Precision TIG-welded for structural integrity and a clean, motorsport-grade finish
• Mandrel-bent tubing ensures optimal exhaust velocity and minimal restriction
• Designed to reduce backpressure and improve turbo spool
• High heat resistance for sustained performance under extreme driving conditions

Performance Benefits

• Improved exhaust flow for enhanced horsepower and throttle response
• Reduced system weight for sharper handling and acceleration (titanium configuration)
• Faster turbo spool and improved mid-to-high RPM responsiveness
• Enhanced driver engagement through sharper sound and feedback

• All required clamps, hardware, and gaskets
• Plug-and-play valve integration components (valved configurations)
• Installation guide

Why This System

The 991 Turbo S was engineered to deliver world-class performance in almost any condition — but the factory exhaust keeps the flat-six's character in check. This system removes that ceiling, delivering a more aggressive, more responsive, and more emotionally engaging driving experience.

For owners who expect their Turbo S to sound as serious as it drives — this is the upgrade that defines it.
