Transform the performance character of your 2019-2024 McLaren GT M840T and 2024+ McLaren GTS M840T with the Redstar performance exhaust system, precision built for the 4.0L V8 twin-turbo platform. The M840T responds exceptionally well to exhaust upgrades, and this system is engineered to let that responsiveness shine while elevating the carÕs acoustic personality.

With free-flow 3 inch piping in robust 2.0mm 304 stainless, the Redstar system targets backpressure reduction to unlock significant power gains, faster turbo spool, and crisper throttle response. Pair it with RedstarÕs OEM-Style Heat Shielding to cut radiant exhaust heat by up to 80%, helping control engine bay temperatures and supporting long-term turbo health. Expect meaningful weight reduction and a richer, more race-inspired exhaust note that complements the GT and GTS driving experience.

Every Redstar system reflects a focus on durability, performance, and sound quality. Optional material upgrades include Titanium for ultimate lightness and Inconel 625 for a high-pitched exotic tone with outstanding longevity. Crafted to RedstarÕs high standards, this is the definitive performance exhaust upgrade for McLaren GT and McLaren GTS owners seeking precision engineering, unmistakable sound, and enduring quality.

Available Options

• OEM-Style Heat Shielding: Redstar's signature thermal management system reduces radiant exhaust heat by up to 80%. Developed with motorsport-inspired materials and construction, it uses a multi-layer design of ceramic insulation and embossed stainless steel foil. Unlike wraps or coatings that degrade quickly, Redstar shielding delivers long-term durability and consistent protection for engine bay components.
• Titanium: The ultimate lightweight material, delivering a distinct, exotic exhaust character while helping shed mass. Its intrinsic acoustic qualities produce an authentic, engaging note aligned with high-performance driving.
• Inconel 625: Produces a high-pitched, ripping exotic sports car sound while outperforming stainless steel in both weight reduction and sound quality. Remarkably, it is rated at 100 times the durability of titanium, delivering peak longevity alongside standout tone.
