Kline Innovation Valvetronic Exhaust System for Lamborghini Urus
The Urus, Lamborghini’s first venture into the SUV market, is a powerful and capable utility vehicle that showcases Italian automotive ingenuity. However, Kline recognized that the sound it produced was somewhat lacking, failing to truly capture the essence of this formidable Bull.
The Sound
- To address this, Kline implemented a significant improvement by replacing the restrictive factory catalysts with either 100 or 200 cell HJS HDPE motorsport catalysts. This modification not only opened up the sound but also incorporated a 20-degree X-pipe to blend the exhaust gases out of phase, raising the pitch of the exhaust note and eliminating unwanted drone.
- In the rear section, Kline utilized the car’s stock electronic valve control system. When the valves are closed, the gases are directed through a series of chambers and acoustic fill sections, ensuring a smooth and quiet ride during cruising. However, when the valves are open, the silencer is completely bypassed, allowing for an unhindered and commanding roar that perfectly matches the Urus’s true character.
Performance
- Kline’s performance enhancements involved the removal of restrictions from the silencer section and the implementation of a completely free-flow system under valve open. As a result, the exhaust operates at optimal efficiency, delivering moderate power and torque gains that enhance the Urus’s overall performance.
- With the addition of racing pipes, expect an impressive increase of 37 horsepower and 48 Nm of torque.
Stainless Steel
- In the domain of exhaust manufacturing, Kline adheres to the long-standing industry standard of utilizing 304-grade stainless steel. This grade offers a balanced combination of moderate strength, thermochemical stability, cost-effectiveness, and ease of production, ensuring the construction of exhaust systems that embody a practical fusion of affordability, functionality, and durability. It is important to note that stainless steel, despite its density being similar to regular steel, is relatively heavier compared to alternative materials. Additionally, it possesses slightly lower tensile strength, which imposes certain limitations when aiming to create high-performance exhaust components capable of producing vibrant and captivating exhaust notes.
Inconel
- When prioritizing durability and heat resistance, Kline turns to the ultimate choice: Inconel 625, widely employed in the aerospace industry. This exceptional material finds extensive application in the manufacturing of critical components, particularly exhaust turbine blades for high-performance jet engines. Inconel is highly favored in Formula One exhaust systems and has been selected by manufacturers involved in prestigious hypercar projects such as the McLaren P1 and Aston Martin 177. The advantages of Inconel lie in its exceptional tensile strength and thermochemical stability. Comparable to titanium in terms of tensile strength, Inconel achieves an outstanding strength-to-weight ratio, allowing for the utilization of thin sidewall materials while upholding structural integrity. This facilitates the production of lightweight components that exhibit remarkable resistance to fatigue over prolonged periods. However, working with Inconel presents challenges due to its difficult machinability and specific welding requirements, demanding specialized skills and time-consuming techniques. Moreover, the unique properties and specialized manufacturing processes associated with Inconel contribute to its higher cost as a raw material.

Frequently Asked Questions
- Does the Kline Innovation Valvetronic Exhaust System fit my Lamborghini Urus? Yes. This system is engineered specifically for the Lamborghini Urus from 2018 onward with the 4.0L twin-turbo V8. It uses the vehicle’s stock electronic valve control system rather than a separate controller, so the factory valve behavior is retained. Confirm your vehicle is the Urus before selecting downpipe options, since the options are model-specific.
- Are the downpipes included with the system? No. The downpipes are optional and not included as part of the standard kit, even though some images may show them. Downpipe options are selected separately at checkout. The downpipe heat-shield is compatible only with the 100-cell and 200-cell catted downpipe options. Confirm your downpipe selection before ordering so you receive the complete setup you expect.
- How much power does the Kline Innovation Valvetronic Exhaust System add to the Urus? With the racing pipes configuration, Kline reports an increase of 37hp and 48nm of torque, the largest gains of any application in the range thanks to the twin-turbo V8. All cross sections are enlarged roughly 10 percent over the stock configuration for the best balance of torque and increased power. Catted configurations deliver moderate gains with the sports cats in place.
- What is the Kline Innovation Valvetronic Exhaust System made from? Buyers choose between two materials. The standard version uses 304-grade stainless steel, which balances durability with cost. The premium version uses F1-grade Inconel 625, an aerospace superalloy with a tensile strength comparable to titanium and superior heat and fatigue resistance. The Inconel range delivers the best strength-to-weight ratio Kline offers, using thin sidewall material while keeping structural integrity.
- How does the Kline Innovation Valvetronic Exhaust System sound at cruise versus wide open? With the valves closed, gases route through a series of chambers and acoustic fill sections for a smooth, quiet cruise. With the valves open, the silencer is completely bypassed for an unhindered, commanding roar. The 20-degree X-pipe blends the exhaust gases out of phase to raise the pitch and eliminate unwanted drone, matching the Urus’s character.
- Is this exhaust legal in my state? This system is not CARB approved, so it cannot be sold in California or other states requiring CARB certification. No assessment has been made regarding EPA anti-tampering compliance; only that the required testing and validation have not been completed. Check with your local enforcement officials to confirm the legality of use where you live before purchasing.
