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.

DOES MY CAR HAVE "PSE"?


The Porsche Sport Exhaust – better known as PSE – was a factory option available on many late model Porsches. You can quickly and easily determine if your vehicle is equipped with PSE by taking a look at your center console. If your console has a button on it with an "exhaust tip" icon (see photo), then your vehicle is equipped with PSE, and you should select the PSE option when adding this product to your cart. If you do not see this button, the your vehicle does not have PSE and you should select the standard exhaust option when checking out.

NOTE: Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only. If you are located outside the UK, please consult your local laws and regulations to ensure compliance.
