TNEER Valvetronic Exhaust System for Rolls Royce Cullinan 2019+
The Rolls-Royce Cullinan is built around a front-mounted 6.75-litre twin-turbocharged V12 producing 563 horsepower, the most powerful and most refined engine configuration Rolls-Royce has ever fitted to a road car. The Cullinan's V12 is engineered around an entirely different set of priorities than any other performance SUV platform, where acoustic refinement, mechanical isolation, and the complete absence of NVH are the primary engineering objectives rather than power output or throttle response. The exhaust system on the Cullinan is consequently among the most heavily managed in the luxury segment, tuned to suppress rather than present the V12's acoustic character at every operating condition. TNEER engineers this valvetronic system specifically for the Cullinan, with tube routing, X-pipe placement, and mounting geometry developed to the exact underbody architecture of the platform.
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 weld joints and flow disruptions of multi-segment construction. The mid X-pipe is integrated at the mid-system junction, cross-linking both exhaust banks to balance pulse energy between the V12's cylinder groups. On a twin-turbocharged twelve-cylinder of this displacement and configuration, mid-system scavenging through an X-pipe contributes to exhaust flow efficiency and the tonal coherence of the note across the operating range, allowing the Cullinan's V12 to express a more defined acoustic character than the factory system permits at any throttle position. The system installs to all factory mounting locations, requiring no structural modification and maintaining correct chassis alignment throughout.
The valvetronic rear mufflers give the driver direct control over acoustic output from a single system. Valves closed, the exhaust maintains the composed, whisper-quiet refinement that defines the Cullinan's character at any speed and in any driving condition, presenting the V12's presence without intruding on the cabin environment the Cullinan is engineered to deliver. Valves open, the full acoustic output of the 6.75-litre twin-turbocharged V12 is presented without the attenuation the factory system imposes, revealing a twelve-cylinder acoustic character that the standard Cullinan exhaust is specifically designed to prevent the driver from hearing. On a vehicle at this price point and specification level, that distinction is deliberate and significant.
Optional TACS | TNEER App Control System:
For owners who want direct, independent control over valve position beyond what the vehicle's existing architecture provides, TNEER offers the TACS, their proprietary App Control System, as an optional addition. The TACS allows manual valve control through a dedicated application interface, giving the driver full authority over exhaust valve position at any time regardless of driving mode or vehicle operating condition. For a platform where the factory exhaust management is as conservative as the Cullinan's, the TACS provides the most direct and complete control over acoustic output available for this application.
About TNEER:
TNEER is built around a single engineering conviction: the exhaust system is not a peripheral component. It is the primary interface between the engine and the driver's experience of it. Every system TNEER produces is developed to bring out the true voice of the engine it is built for, improving exhaust flow and delivering a distinct tone that is mechanical, raw, and directly connected to the character of the car.
The manufacturing process that defines TNEER's fitment standard is their high-tech robotic pipe bending technology. Rather than fabricating exhaust routing from multiple welded sections, TNEER forms each tube from a single continuous piece, bending high-grade material to navigate the spatial constraints of each specific engine bay without the diameter reductions, flow disruptions, and structural inconsistencies that welded multi-piece construction introduces. The result is an exhaust system with continuous tube geometry, perfect fitment to the platform it is built for, and no compromises in the routing that precision bending makes unnecessary.
For enthusiasts who regard sound and performance as inseparable elements of the driving experience, TNEER engineers each system to deliver both from the first throttle input.
