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
