Titanium Exhaust Sleeve – Catalytic Converter to Rear Silencer Grade 5 Titanium (Ti-6Al-4V) Porsche 996 / 997 / 991 

Replaces Porsche Part Number: 99711152000 

This Grade 5 titanium exhaust sleeve connects the catalytic converter to the rear silencer and represents a significant upgrade over the original Porsche steel sleeve and conventional aftermarket alternatives. Manufactured from aerospace-grade Grade 5 titanium (Ti-6Al-4V), this Rohler exhaust sleeve delivers exceptional strength, corrosion resistance, and weight reduction, making it the ideal long-term solution for performance-focused and enthusiast-owned Porsches. Unlike the original OE clamp, which is susceptible to corrosion over time, this titanium version is highly resistant to salt water and corrosive environments at temperatures below 300°C, ensuring outstanding longevity. 

Precision-engineered for accurate fitment across multiple Porsche generations, this upgraded sleeve fits 996, 997, and select 991 Carrera models, offering broader compatibility than many aftermarket options while retaining true bolt-on installation. 

Grade 5 titanium (Ti-6Al-4V) construction 

Stronger, lighter, and more corrosion-resistant than OEM steel sleeves 

Superior longevity compared to original and aftermarket versions 

Direct replacement for Porsche 99711152000 

Precision fit with excellent sealing Suitable for standard and factory sport exhaust systems 

Ideal for performance, restoration, or preventative maintenance
