TNEER Valvetronic Exhaust System w/Tips for McLaren 570s 2015-2021

TNEER - The Next Exhaust Engineer:

The McLaren 570S is built around a 3.8-litre twin-turbocharged V8 producing 562 horsepower, positioned mid-ship in McLaren's carbon fiber MonoCell II chassis. The Sports Series platform shares its fundamental twin-scroll turbocharger architecture with the Super Series but presents its own distinct packaging geometry, with exhaust routing constraints specific to the 570S's rear subframe and underbody layout. TNEER engineers this valvetronic system specifically for the 570S, with tube geometry, race pipe configuration, and mounting points developed to the exact spatial constraints of the McLaren Sports Series platform rather than adapted from a broader McLaren application.

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 of multi-segment welded construction. The race pipes address the primary restriction point in the exhaust path, removing the factory catalytic converters immediately downstream of the turbocharger outlets where back pressure has the most direct effect on turbine behavior and spool characteristics. On a twin-turbocharged platform, the relationship between downstream restriction and turbocharger efficiency is immediate and measurable. Reduced back pressure at the race pipe location translates directly to faster spool, improved mid-range torque delivery, and sharper throttle response across the rev range.

The system installs to all factory mounting locations, requiring no structural modification to the 570S chassis and maintaining correct alignment throughout. High-grade stainless-steel construction across both the valvetronic system and race pipes provides the thermal stability and corrosion resistance the twin-turbo V8's sustained heat output demands. In the confined rear section of a mid-engine platform where exhaust components operate in close proximity to structural and drivetrain elements, long-term thermal integrity is a fundamental design requirement.

The ECU-controlled valvetronic muffler integrates with the 570S's existing driving mode architecture, adjusting valve position in response to the selected mode without secondary controllers. Valves closed, the system maintains a composed tone appropriate for daily and road use while retaining the character of a turbocharged V8 operating without significant exhaust restriction. Valves open, the full acoustic output of the 570S's V8 is unobstructed. The McLaren twin-turbo V8 has a distinct sonic character at full throttle under race pipe configuration that the factory exhaust system is specifically calibrated to suppress. This system removes that suppression entirely.

Optional Downpipe Configurations:

For owners seeking maximum performance extraction, TNEER offers two downpipe specifications that address the primary restriction point in the McLaren 570S 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 Ferrari’s 3.9L 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
