Velocity Exhausts Mclaren MP4 12C / 650S Exhaust System

McLaren MP4-12C / 650S Catback Exhaust System

Built for the twin-turbo 3.8L V8 that started McLaren's modern supercar era, this catback exhaust system is engineered to unlock the full voice of the MP4-12C and 650S. The factory setup keeps the V8 muted. This system removes that restriction, delivering a sharper, louder, more exotic soundtrack that matches the car's performance.

Sound Character

The twin-turbo V8 has far more voice than the factory system lets through. This system lets it out.

• X Pipe Design: Improves scavenging between banks for a smoother, higher-pitched, more exotic tone while cutting the muted factory sound.
• F1 Catback: A sharp, motorsport-inspired note with exceptional clarity through the rev range, with valves for full control over volume.
• Race Catback: The loudest and most unfiltered option, with a raw, track-inspired sound.
• Overrun Character: Aggressive crackles and pops on deceleration and rapid gear changes, most pronounced with the Downpipes upgrades.
• Overall Profile: Lightweight, high-revving, and mechanical, closer to a GT race car than a road-going supercar.

Why This System

The MP4-12C and 650S were engineered around extreme efficiency and performance, but their factory exhaust understates the V8's true character. This catback system removes those limitations, delivering a more exotic, more responsive, and more emotionally engaging driving experience.

For owners who expect their McLaren to sound as advanced as it performs, this is the upgrade that defines it.
