SS304 High-Flow Catless Downpipes for Porsche Panamera 971 2.9T Twin-Turbo V6 OPF Models
Designed for the Porsche Panamera 971 2.9T powered by the 2.9L twin-turbo V6 and equipped with OPF / GPF, these high-flow catless downpipes replace the restrictive factory catalytic converter sections with a significantly freer-flowing exhaust path directly after the turbochargers.
Manufactured from high-quality SS304 stainless steel, the downpipes are engineered to withstand extreme exhaust temperatures while providing excellent strength, corrosion resistance and long-term durability.
The catless configuration removes the restrictive factory catalytic converters, significantly reducing post-turbo exhaust restriction and allowing exhaust gases to flow more efficiently. This results in increased turbocharger sound together with a deeper, louder and more aggressive twin-turbo V6 exhaust tone.
The freer-flowing design is particularly suited to tuned and performance-oriented Porsche Panamera 971 2.9T builds where reduced exhaust restriction and improved turbocharger response are a priority.
Vehicle-specific routing, flange geometry and mounting points are designed around the factory Porsche Panamera 971 2.9T exhaust system. Original sensors and applicable OEM components should be transferred during installation where required. Professional installation is strongly recommended.

OPF / GPF FITMENT GUIDE:
OPF / GPF is most commonly found on European-market petrol vehicles. Many U.S. and Canadian-spec vehicles are supplied without OPF / GPF, even when the model and year are similar.
These downpipes are specifically designed for OPF / GPF-equipped vehicles. If you are unsure which version your car has, we recommend confirming the emissions configuration by VIN or checking the factory exhaust system before ordering.
IMPORTANT NOTICE:
This product is intended for off-road, track and motorsport use only. Removal of the factory catalytic converters may not comply with emissions or public road-use regulations in your country or region.
Installation of catless downpipes may trigger a Check Engine Light (CEL). Appropriate ECU software or calibration may be required depending on the vehicle setup.
It is the customer’s responsibility to confirm all applicable local emissions, inspection and road-use regulations before purchasing or installing this product.
