Range Rover Defender OCTA Primary Downpipes
The RedStar Exhaust Primary Downpipes for the Range Rover Defender OCTA 4.4L V8 are engineered to deliver increased performance and a much more aggressive exhaust sound without replacing the entire exhaust system. Featuring a flow-optimized design and precision fitment, these downpipes install as a direct bolt-on solution, significantly reducing backpressure and improving exhaust efficiency.
The result is sharper throttle response, improved performance, and a louder, more commanding exhaust noteβmaking this the ideal first exhaust modification for the Defender OCTA powered by BMWβs 4.4L V8.

- OEM-style Heat Shielding- 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.
