SPOOL McLaren 750S X-Cross Race Exhaust | 304 Stainless Muffler Delete

SPOOL McLaren 750S X-Cross Race Exhaust

The SPOOL 750S X-Cross replaces the restrictive factory rear silencer section with a straight-through, crossover-style 304 stainless steel assembly. Removing the OEM muffler's internal baffling lets the twin-turbo V8 breathe freely through the final section of the exhaust, sharpening throttle response and unlocking the deeper, harder-edged tone the stock system keeps muted.

Flow & Design

Rather than simply opening up the outlet, the X-Cross is built around a crossover center section that merges both banks ahead of the tips. Balancing pressure pulses between banks keeps exhaust flow stable and evens out the note, so the gain is in flow quality — not just volume.

• X-Cross center section equalizes pressure pulses between banks
• Mandrel-bent tubing holds full internal diameter through every bend
• Consistent cross-sectional area avoids sudden restrictions and pressure drops
• Straight-through path with no packing, baffles or restrictive chambers

Sound

Substantially deeper and more aggressive than stock, with a hard mid-range edge that builds cleanly with revs. The X-Cross geometry gives the 750S a more focused, purposeful pitch than a simple muffler delete, which tends to sound flat and uneven by comparison.

Construction

• 304 stainless steel construction for heat and corrosion resistance
• Full TIG welding for clean, durable, leak-free joints
• Twin stainless flex sections absorb engine movement and thermal expansion
• Polished straight-cut tips set against the brushed pipework
• Factory hanger locations retained for correct alignment

Installation

Direct bolt-on using the factory mounting points and supplied clamping hardware. No cutting, welding or permanent modification is required, and the OEM section can be refitted at any time.
