BJG Race Downpipes: Porsche Cayenne S 2.9TT - Heat-Shielded Stainless Steel

Give the Cayenne S's twin-turbo V6 a more commanding voice with BJG heat-shielded stainless steel race downpipes. This matched pair replaces the factory downpipe sections immediately after the turbochargers, opening the exhaust path at its source for a sharper, more assertive sound under load.

The free-flowing race configuration is designed to reduce exhaust restriction and support the engine's performance potential with a properly matched ECU calibration. Stainless steel construction, formed bends and integrated outer heat shields give the pair a purposeful finish, while the visible weldwork and BJG branding carry the detail through to the hardware.

Highlights

• Matched left and right race downpipes for the Porsche Cayenne S 2.9L twin-turbo V6.

• More pronounced turbo and exhaust character, with final sound dependent on the rest of the exhaust system.
• Free-flowing turbo-outlet design to support a calibrated performance build.
• Sensor provisions and flanged connections as shown in the product photos.
