This high-quality exhaust connecting sleeve joins the catalytic converter to the rear silencer on Porsche 996 and 997 models, offering a superior solution compared to the original Porsche part and many aftermarket alternatives.

Manufactured to tighter tolerances and improved material quality, this upgraded exhaust sleeve provides a more precise fit, improved sealing, and enhanced durability over time. Unlike the original OE sleeve – which can be prone to corrosion and fitment issues as the vehicle ages – this version is designed to deliver long-term reliability and ease of installation.

Crucially, this sleeve is engineered to fit both Porsche 996 and Porsche 997 applications, making it a more versatile and cost-effective option than other aftermarket versions that are often model-specific or require modification.
