McLaren 750S Spool X-Cross Race Exhaust

The Spool X-Cross race exhaust for the McLaren 750S replaces the factory rear silencer with a straight-through 304 stainless crossover assembly for a deeper, harder-edged sound.

Why you need it

The stock muffler baffling keeps the twin-turbo V8 muted. The X-Cross center section merges both banks ahead of the tips to balance pressure pulses, so flow stays stable and the note stays even rather than just getting louder. The result is sharper throttle response and a focused, aggressive tone that builds cleanly with revs.
