TNEER Valvetronic Exhaust System w/Tips for McLaren 720s 2017-2023

TNEER - The Next Exhaust Engineer:

The McLaren 720S is built around a 4.0-litre twin-turbocharged V8 producing 710 horsepower, housed in a carbon fiber monocoque chassis where packaging constraints around the drivetrain are more demanding than virtually any comparable mid-engine platform. The M840T engine's twin-scroll turbocharger configuration and the 720S's extremely tight rear mid-section present specific exhaust routing requirements that demand precision at every bend and junction in the system. TNEER engineers this valvetronic exhaust specifically for the 720S platform, with tube geometry, mounting points, and system architecture developed to the exact spatial constraints of the McLaren's carbon tub and rear subframe architecture.

Each section is formed from single-piece high-grade stainless-steel tubing using robotic pipe bending technology, producing continuous tube geometry throughout the system without the diameter reductions and flow disruptions introduced at welded junctions in multi-segment construction. On a twin-turbocharged platform with twin-scroll turbocharger architecture, exhaust gas pressure consistency and back pressure reduction downstream of the turbine outlets directly influences turbocharger efficiency, spool characteristics, and mid-range torque delivery under sustained load. The system installs to all factory mounting locations, requiring no structural modification to the 720S chassis and maintaining correct alignment throughout the rear subframe.

The ECU-controlled valvetronic muffler integrates with the 720S's existing Active dynamics panel architecture, adjusting valve position in response to the selected driving mode without secondary controllers or aftermarket modules. Valves closed, the system delivers a composed tone appropriate for road use while retaining the inherent character of a high-output twin-turbocharged V8 at partial throttle. Valves open, the full acoustic output of the M840T at full load is unobstructed. The 720S's V8 has a distinct acoustic signature at full throttle that differs from both Ferrari and Lamborghini forced-induction platforms. This system is built to present that character without the suppression the factory exhaust imposes.

High-grade stainless-steel construction provides thermal stability and corrosion resistance to the twin-turbo V8's sustained heat output demands. On a platform where the engine and exhaust system occupy an exceptionally confined space within the rear bodywork, long-term thermal integrity is a design requirement, not a secondary consideration.

Optional Downpipe Configurations:

For owners seeking maximum performance extraction, TNEER offers two downpipe specifications that address the primary restriction point in the McLaren 720S exhaust path.

• The race downpipes remove the factory catalytic converters entirely, delivering the most direct reduction in exhaust back pressure available on this platform. The effect is measurable at the turbocharger level, where reduced downstream restriction translates to faster spool, improved mid-range torque delivery, and sharper throttle response across the rev range.
• The 200-cell sport downpipes retain a high-flow catalytic substrate, reducing restriction significantly compared to the factory units while maintaining a level of emissions compliance suitable for owners who require it. For street-driven builds where race downpipes are not practical, the 200-cell specification represents a meaningful performance upgrade within a more usable operating profile.

Both downpipe options are constructed from high-grade stainless steel and engineered to the same fitment standard as the catback system.

Quantum Ceramic Coating (QCC):

TNEER's proprietary Quantum Ceramic Coating is a three-layer ceramic particle application developed specifically for high-output exhaust environments. The specification exceeds standard ceramic coating performance across every measurable category relevant to a performance exhaust system.

QCC handles 50% more heat than conventional ceramic coatings, a critical advantage on a system managing the thermal output of a twin turbo V8 under sustained performance driving conditions. Hardness and wear resistance are improved by 30% over standard ceramic alternatives, ensuring the coating maintains its integrity through the repeated heat cycling that track and spirited road use demands. At 50% lighter than a typical exhaust thermal shield, QCC delivers thermal management without adding mass back into a system engineered for weight efficiency.

The result is a finish that performs structurally and presents visually over the long term, without the degradation, flaking, or discoloration that standard coatings exhibit under sustained high-temperature exposure.

The Art Of Sound:

In 1913, Luigi Russolo published The Art of Noises. His work explored how the industrial revolution changed the way people experience sound. Engines, machines, and mechanical movement created a new soundscape that went far beyond traditional music. Russolo believed these mechanical sounds represented the future of how people would hear and appreciate the world around them. That same philosophy connects directly with TNEER exhaust systems. Performance cars are not only about speed or appearance. Sound plays a major role in the driving experience. A well designed performance exhaust transforms the character of the car every time the engine starts. TNEER engineers focus on building high performance exhaust systems that bring out the true voice of the engine. Each system is designed to improve exhaust flow while delivering a distinct tone that drivers can feel from the first throttle input. The result is an exhaust note that feels raw, mechanical, and deeply connected to the car itself. For enthusiasts who value performance and sound, TNEER creates an experience that goes far beyond standard factory exhaust systems.

Note:

• Downpipes are not CARB certified and may not be legal for use on emissions controlled vehicles; intended for off road use only.
• Valves are ECU controlled
