Titanium Cat-Back Exhaust McLaren 650S

This titanium cat-back exhaust system is engineered for the McLaren 650S, built around the 3.8L twin-turbo V8 platform shared with the MP4-12C.

It replaces the rear exhaust section with a full titanium, high-flow valved system, focusing on weight reduction, sharper turbo response, and a more exotic exhaust character.

High-end systems like this typically use 76mm titanium piping and OEM-style valve control to balance daily drivability with track-level sound and performance
