Porsche 991 Turbo S Titanium Valved Catback Exhaust System

Porsche 991 Turbo S Titanium Exhaust System

Built for one of the most capable twin-turbo platforms ever produced, this titanium exhaust system refines and amplifies the Porsche 991 Turbo S into something sharper, lighter, and far more emotional. It delivers the perfect balance of exotic sound, improved flow, and reduced weight—without compromising daily drivability.

Pricing

• Catless Titanium System: $4,599.99
• Catted Titanium System (High-Flow): $4,899.99

Fitment

• Porsche 911 Turbo S (991.1 & 991.2 | 2014–2019)
• Direct bolt-on exhaust system — no cutting or permanent modifications required
• Precision-engineered for OEM mounting points and factory alignment
• Fully compatible with OEM exhaust valve controls and drive modes

Sound Character

The 991 Turbo S is fast from the factory—this system gives it a voice to match.

• Valves Closed: Refined, deep tone with a controlled, premium presence. Ideal for highway cruising with minimal drone.
• Valves Open: Aggressive, exotic turbocharged sound with sharper spool, cleaner turbo acoustics, and a more pronounced high-RPM character. Enhanced overrun crackles and a more engaging throttle response.
• Catless Configuration: Maximum volume and raw turbo character—louder spool, more aggressive pops, and a more motorsport-inspired edge.
• Catted Configuration: Balanced performance with smoother delivery, reduced harshness, and a more refined exotic tone while retaining strong volume.
• Overall Profile: Titanium enhances higher-frequency detail, making the Turbo S sound more exotic, responsive, and less muted than OEM.

Why This System

The 991 Turbo S is a benchmark in performance engineering—but its factory exhaust leaves untapped acoustic and weight potential on the table. This titanium system removes those limitations, delivering a lighter, faster-responding, and far more engaging driving experience.

For owners who want their Turbo S to sound as advanced as it performs—this is the upgrade that defines the car.
