The McLaren 720S center quad exhaust conversion by ZACOE reshapes the rear end with a 765LT-style quad layout and introduces a sharper visual and acoustic profile. First revealed at SEMA 2022 on the Galaxy Widebody 720S, a standout collaboration with Creative Bespoke, the conversion removes the traditional side-exit layout in favor of a center-mounted system. The result matches the aggression of a track-spec build with show-quality execution.
At the core of the upgrade is the Fi EXHAUST system, designed specifically for the 720S platform and constructed from high-grade T304 stainless steel. The system includes a Valvetronic muffler that regulates airflow and backpressure based on driving conditions and mode selection. Internal design and flow routing are tailored exclusively for the McLaren 720S Coupe and Spider, resulting in a seamless blend of performance gains and refined tone.
Fi EXHAUST offers two configurations: a non-valved version for drivers prioritizing weight savings and maximum sound output, and a valved version with two control options. One version uses the factory valve motors to retain OEM drive mode functionality, while the other integrates Fi’s proprietary remote control system, ideal for models not equipped with factory Valvetronic controls. Both deliver a dynamic sound range, from restrained during city driving to aggressive under full throttle.
Closed valves increase exhaust back pressure, which enhances torque delivery at lower RPMs. When opened, the system allows for a freer flow of gases, boosting horsepower in the higher rev range while releasing a deeper, more resonant exhaust note. Estimated power gains range from 5 to 10 percent when the system is paired with a catless downpipe and ultra-high-flow components. Sound quality also benefits from Fi’s custom muffler internals, which are tuned specifically for the 4.0L twin-turbo V8 M840T.
Titanium quad tips finish the system, chosen not only for aesthetics but also to match the aggressive tone and reduce rear-end weight. These tips are paired with a ceramic-coated aluminum insert that shields the carbon bumper from thermal stress. A protective clear coat applied to the carbon surfaces ensures long-term resistance to UV rays and discoloration.
ZACOE’s approach to carbon aero and structural upgrades begins with over 40 hours of 3D scanning on a full OEM McLaren 720S chassis. This process captures exact dimensions of the exterior, allowing designers to engineer every part around factory tolerances. After scanning, the team transitions to hand-drawn concept sketches and CAD modeling, followed by aerodynamic simulations to refine airflow and integration.
Prototypes are built from ABS plastic using advanced 3D printing and CNC machining, then tested on the vehicle to verify fitment and heat tolerance. Molds are then created for final carbon fiber production, ensuring every panel matches the precision of the scanned data.
The finished kit includes the carbon fiber rear bumper upper center section, a reinforced aluminum insert, an aluminum mesh grille, structural brackets, and all necessary hardware. The carbon pieces have a visible weave, are cured for strength and durability, and are designed for bolt-on installation. The Fi valvetronic muffler mounts behind the new center panel, with quad titanium tips exiting through the reshaped opening.
The complete ZACOE McLaren 720S center quad exhaust conversion kit is available exclusively through Bulletproof Automotive. Each kit is built to order in Germany, with air express shipping arranged directly from the manufacturer. Due to fluctuating freight and customs costs, all shipping rates and lead times are confirmed prior to finalizing the build order with the factory. This conversion delivers a complete package for owners who want to enhance their 720S with 765LT-inspired design, lightweight carbon construction, and a fully engineered Fi EXHAUST system.
