The Lamborghini Urus carved out its own path as the brand’s first SUV, combining aggressive styling with supercar-like performance in a practical package. Yet even with its twin-turbo V8, one element felt restrained, the exhaust note. Kline Innovation set out to change that with its Valvetronic Exhaust System for the Lamborghini Urus, engineered to unlock both performance and emotion in equal measure.
The Urus redefined what an SUV could be, blending daily practicality with supercar DNA. Its twin-turbo V8 and advanced all-wheel drive system give it staggering acceleration, yet many enthusiasts felt its exhaust tone fell short of Lamborghini’s legacy. Kline steps in with a solution crafted for purists.

From the beginning, Kline’s mission was to address the factory system’s muted character. The solution came through a series of precise upgrades, starting with the restrictive OEM catalysts. By offering 100 or 200 cell HJS HDPE motorsport catalysts, Kline allows owners to tailor the system for either aggressive race-focused use or a more balanced setup for spirited street driving.
A 20-degree X-pipe blends exhaust pulses out of phase, raising the pitch while cutting out unwanted drone. The result is a sharper, more visceral sound profile that reflects the Urus’s true identity.
Kline retains full use of the factory electronic valve control, ensuring daily usability remains intact. With valves closed, gases are routed through chambers and acoustic fillers for quiet cruising. Open the valves, however, and the silencer is bypassed completely, letting the 4.0L twin-turbo V8 roar with authority.
Kline didn’t stop at sound. By removing restrictions and creating a fully free-flow path under valve-open conditions, the system sharpens throttle response and efficiency. With the addition of racing pipes, gains of 37 horsepower and 48 Nm of torque are on the table, making the Urus even more formidable on both road and track.
Cross sections have been increased by around 10 percent compared to stock, striking the ideal balance between mid-range torque and high-rpm power. The silencer section measures 70mm, valve closure transits at 57mm, and valve-open passages remain at a full 70mm free flow. Every detail is optimized for both flow and usability.
Kline provides two material choices, each with its own philosophy. The first is 304-grade stainless steel, the proven industry standard. It offers durability, affordability, and stability while delivering strong performance. However, it comes with added weight and lower tensile strength compared to exotic alternatives.
For those seeking the ultimate, Kline offers F1-grade Inconel 625. Used in aerospace turbine blades and Formula One exhausts, Inconel thrives under extreme heat and pressure. Its strength-to-weight ratio enables thin-walled construction without compromising integrity, resulting in a system that is both lighter and longer-lasting than steel. The tradeoff lies in cost and complexity, as Inconel requires specialized machining and welding techniques.
Every Kline exhaust is the result of complete in-house development. Laser scanning ensures precise fitment, while CNC laser cutting, mandrel bending, silencer production, CNC welding, and even autoclave carbon fiber work are all part of Kline’s capabilities.
Kline has delivered for clients ranging from W Motors’ Fenyr Supersport to RUF and Corbellati. Their Lamborghini Urus system benefits directly from this expertise, balancing artistry and functionality.
For additional control, Kline offers the INCONEL BUTTON wireless kit, allowing owners to open and close valves at will. While optional downpipes may appear in photos, they are not included with the standard kit.
Bulletproof Automotive offers the Kline Valvetronic Exhaust System for the Lamborghini Urus to enthusiasts seeking to amplify their SUV’s presence. With its combination of Italian design, aerospace materials, and race-bred engineering, this system transforms the Urus from impressive to unforgettable.
