Porsche 971.1 Panamera 4|4S E-Hybrid Secondary Downpipes
Enhance your Porsche 971.1 Panamera 4 / 4S Twin-Turbo 2.9L V6, including E-Hybrid models, with RedStar Exhaust Secondary Downpipes. Designed to replace the restrictive factory secondary catalytic converters, these flow-optimized downpipes are precision-engineered to integrate perfectly with the OEM split exhaust design.
This fully bolt-on upgrade significantly improves exhaust flow and overall performance while maintaining no check engine light (CEL) issues. The result is improved throttle response, increased driving engagement, and a deeper, more aggressive exhaust character—delivering a seamless performance upgrade without compromising reliability or fitment.

Available Options:
- OE-style Heat Shielding with ceramic inner liner - signature REDSTAR thermal management feature that reduces radiant heat from the exhaust pipes up to 70-80%. Being inspired by racecar engineers who uses it alot, we moved heat shielding to the tuning industry and made it available as an option for any REDSTAR products. Usual thermal wraps or ceramic coatings are not even close in effectiveness and durability to our Heat Shielding. Please be aware of fake shielding when it is nothing but foil wrapped around the pipe. Without a sufficient ceramic wool layer inside and properly embossed foil it will not work as expected.
