McLaren MP4-12C / 650S – Valved Exhaust System

T304 Stainless or Titanium – F1-Inspired Acoustics

Overview
The MP4-12C and 650S deliver mind-bending performance, but the 3.8L V8 doesn’t sound the part. The Valvetronic Designs Valved Exhaust System corrects this flaw, unlocking a naturally aspirated, F1-inspired sound. Built from turbo V-bands to tips in full 3.0" diameter, the system merges raw power with refined engineering.
