McLaren 750S Titanium Catback Exhaust | WSTN Performance (M840T P14)

The M840T makes 740 BHP in stock form. The factory exhaust stops it sounding like it should. WSTN Performance titanium catback for the McLaren 750S Coupe and Spider. Built from motorsport-grade titanium, a direct-fit replacement for the factory system: lighter, louder, and purpose-built to let the 4.0TT V8 breathe the way it was designed to. Every system is quality-checked at our Perth WA facility before dispatch worldwide. Why Upgrade? ✓ Sound Transformation: Removes the acoustic deadening the factory system wraps the M840T in. The twin-turbo V8 note under full load is what this engine was built to produce. ✓ Significant Weight Reduction: Titanium construction saves substantial weight over the factory stainless system. Less unsprung mass, better balance, sharper response. ✓ Reduced Backpressure: Free-flow design improves turbo spool and throttle response across the rev range. ✓ Purple Titanium Finish: Heat-blued titanium delivers the visual contrast the factory exhaust never offered. Visible through the rear diffuser aperture. Key Features & Specs Material: Motorsport-grade titanium, corrosion-resistant and weight-optimised Construction: TIG-welded titanium joints Finish: Purple titanium heat-blued finish Finish Note: Titanium colour may vary slightly between units. The heat-bluing process produces natural variation. Images are representative.
