Redstar McLaren 720S Straight Race Exhaust

Transform the character of your 2017-2022 McLaren 720S 4.0L M840T twin-turbocharged V8 with the Redstar 720S Straight Race Exhaust. This direct muffler-replacement section unlocks an unfiltered, race-bred soundtrack and features lightweight Titanium tips with perforated cores, with Black Ceramic Tips available upon request. It integrates flawlessly with Redstar Downpipes and remains fully compatible with all factory components. The optional 3.5 inch configuration is available in place of the standard 3 inch, and requires matching 3.5 inch Downpipes.

Engineered for free-flowing performance, the straight-through layout reduces backpressure for sharper throttle response, faster turbo spool and significant power gains, while adding a richer, more engaging tone. When specified with Redstar's OEM-style ceramic wool heat shielding, radiant heat can be reduced by up to 80% to help preserve surrounding components and support long-term turbocharger health.

Built for durability and precise fitment, the system uses 2.0mm wall 304 stainless steel, is 100% TIG welded and back purged, and mounts using OEM-spec flanges with all factory-style brackets. As a true bolt-on performance exhaust, this Redstar upgrade delivers motorsport-inspired sound and performance with the quality and reliability enthusiasts expect from Redstar.

Available Options

• Inconel 625 - Engineered for an ultra high-pitched, ripping exotic tone while reducing weight compared with stainless steel. Delivers improved sound quality and outstanding longevity, with durability claimed at up to 100 times greater than titanium.
• Titanium - The ultimate lightweight option that imparts a distinctive, exotic exhaust note while trimming mass. Cannot be heat shielded.
• 3.5" - Upsized primary exhaust tubing in place of the standard 3" option.
• 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."
• Tips - Ceramic Coated Black, Lamborghini Style, 3D Printed. Titanium tips with perforated cores also available, with Black Ceramic Tips on request.
