    McLaren Senna Downpipes

    RS.Senna.DP

    The McLaren Senna is already one of the most extreme track-focused supercars ever built—but RedStar Exhaust 3.5” Performance Downpipes elevate it even further. Engineered for the 4.0L twin-turbo V8, these high-flow downpipes dramatically improve exhaust flow, delivering substantial power gains, faster throttle response, and reduced overall weight.

    The result is an even more visceral driving experience, paired with a raw, race-inspired exhaust note that perfectly matches the Senna’s uncompromising character. Precision-built for optimal fitment and durability, RedStar Downpipes are the ultimate upgrade for owners seeking maximum performance and sound from McLaren’s most iconic machine.

    • 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.
    • Inconel 625- an ideal choice for exhaust systems due to its exceptional high-temperature resistance, corrosion resistance, durability, and strength, ensuring long-lasting performance in demanding conditions.
