Transform your McLaren 650S twin-turbocharged V8 M838T with Redstar's sound-balanced Race-X muffler-replacement performance exhaust. This rear section replaces the factory muffler and bolts directly to the OEM catalytic converters and factory mounts, integrating seamlessly with all stock components for a clean, reversible upgrade.

Engineered to relieve downstream restriction, it delivers significant power gains, faster turbo spool-up and sharper throttle response. The exhaust note gains richness and character without sacrificing refinement, while lower under-bonnet temperatures support turbocharger longevity during hard use.

Built for precision and durability, the system utilises 2.0mm wall 304 stainless steel with 100% TIG welded, back-purged construction, OEM-spec flanges, and brackets mirroring the factory layout. Material options include Titanium for notable weight savings and an exotic timbre, and Inconel 625 for a high-pitched, ripping tone with durability that eclipses titanium. Add Redstar's OEM-style thermal shielding for enhanced heat control. A true bolt-on performance exhaust from Redstar for McLaren 650S owners researching premium performance exhausts and downpipes.

Available Options

• Titanium: Ultra lightweight and inherently resonant, titanium reduces mass while imparting an unmistakably exotic exhaust character. It enhances the auditory experience with a truly authentic performance tone.
• Inconel 625: Produces a high-pitched, ripping exotic sports car sound while cutting weight versus stainless steel. Remarkably, it offers durability claimed at 100 times that of titanium for outstanding longevity.
• 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.
