Transform your McLaren 540C and 570S, 570GT, and 570 Spider with the 3.8L twin-turbocharged V8 M838T using the Redstar Exhaust Race-X muffler-delete. This rear-section system removes the factory muffler to open the flow path and shed weight, delivering a lightweight performance exhaust tailored to the M838T.

By cutting backpressure, the Race-X sharpens throttle response and encourages faster turbo spool, while its X-pipe architecture equalises pulses for a clean, high-energy soundtrack. Expect meaningful power gains and a dramatic reduction in mass compared with the OEM exhaust. Optional double-layer heat shielding protects nearby components and wiring from downpipe radiant heat, dropping surface temperatures by up to 70%.

Built for seamless integration, every assembly installs as a true bolt-on using OEM-style interfaces, then is 100% TIG welded and back purged for strength and longevity. Choose Inconel 625 for a ripping, high-pitch exotic note with exceptional high-temperature and corrosion resistance, and durability that is 100 times greater than titanium, or select Titanium for remarkable lightweight strength and outstanding corrosion resistance. Redstar delivers precision, reliability, and unmistakable sound.

Available Options

• Inconel 625 - Produces a ripping, high-pitch exotic sports car sound and offers exceptional high-temperature resistance, corrosion resistance, durability, and strength. It is 100 times more durable than titanium, making it an ideal long-term choice in demanding conditions.
• Titanium - Combines remarkable lightweight strength with excellent corrosion resistance, enhancing performance and longevity in exhaust applications. (Cannot be heat shielded)
• Double-layer heat shielding - Protects surrounding parts, wiring, and hoses from radiant heat from the downpipes. Integrated thermal insulation reduces surface temperatures by up to 70%, outperforming typical thermal wraps or ceramic coatings. Important for safety and beneficial for engine performance by lowering under-bonnet temperature. Highly recommended, especially for catted downpipes.
