Kline Innovation Valvetronic Exhaust System for Type-42 Audi R8 GT

The Audi R8 5.2L FSI is an impressive supercar that combines a V10 engine, an aluminum monocoque spaceframe, and a captivating design that strikes a balance between boldness and elegance. Notably, it possesses the versatility to be enjoyed as a daily driver. Considering this dual-purpose nature, the sound and performance objectives for the exhaust were evident—to create an exhaust system that delivers a comfortable and refined experience during cruising, while exuding a raw and powerful sound and character when revving at high speeds.

Cross Sections

To achieve an optimal balance between torque and increased power, the cross sections of the exhaust system have been deliberately enlarged by approximately 10% compared to the stock configuration. This intentional modification ensures enhanced performance while maintaining the optimal torque-to-power ratio.

The Sound

Combining Kline’s renowned advancements, the exhaust system incorporates the precise x-pipe geometry that generates their signature fiery roar. Furthermore, it features a valvetronic mechanism, introducing an innovative technology that enables a tranquil and quiet driving experience during cruising, while delivering a captivating, high-pitched, and dynamically resonant vocalization when the valves open. When the valves are closed, the exhaust gases are skillfully redirected through a series of chambers and acoustic segments, effectively eliminating any unwanted noise or resonance within the cabin. However, upon opening the valves, the exhaust system seamlessly transitions into a fully unrestricted flow, optimizing both performance and sound. The gases exclusively pass through Kline’s distinctive x-pipe, artfully enhancing the exhaust note with an intensified pitch.

Performance

Through the removal of constraints in the silencer section and the implementation of a completely unrestricted flow system when the valves are open, the exhaust system attains maximum efficiency. This modification not only optimizes the performance of the exhaust system but also results in moderate enhancements in both power and torque output. 21hp and 27 nm power and torque gain.

Materials

The Kline Innovation Audi R8 exhaust system offers a selection of two materials. Firstly, there is the 304 Stainless Steel variant, weighing around 19.5 kilograms. Alternatively, for individuals seeking to reduce weight, there is the option of the F1 Grade Inconel 625 version, weighing approximately 9.0 kilograms.
- Stainless Steel:
  - 304-grade stainless steel has solidified its position as the predominant industry standard for exhaust manufacturing. This particular type of stainless steel offers a well-balanced combination of moderate strength, thermochemical stability, cost-effectiveness, and ease of production. It enables the construction of exhaust systems that are relatively affordable while delivering a high level of functionality and durability. However, it is important to note that stainless steel is relatively heavy. While it shares a similar density to regular steel, its tensile strength is slightly reduced. This limitation restricts the potential for constructing high-performance exhaust components using stainless steel. Additionally, in terms of sound characteristics, the thicker sidewalls required by stainless steel may result in a slightly less vibrant and dynamic exhaust note compared to the other materials mentioned earlier.
- Inconel:
  - Inconel 625, highly valued for its essential role in the aerospace industry where durability and heat resistance are of utmost importance, is extensively utilized in the production of critical components like exhaust turbine blades for high-performance jet engines. Remarkably, Inconel is also the preferred choice for Formula One exhaust systems and has been selected by manufacturers involved in prestigious hypercar projects such as the McLaren P1 and Aston Martin 177. These applications benefit significantly from Inconel’s exceptional ability to withstand extreme temperatures exceeding 1000°C while prioritizing lightweight design.
  - Inconel showcases exceptional properties, including notably high tensile strength and remarkable thermochemical stability. Its tensile strength rivals that of titanium, resulting in an outstanding strength-to-weight ratio. Consequently, Inconel enables the use of thin sidewall materials while maintaining structural integrity, resulting in the production of lightweight components that resist fatigue over time. However, working with Inconel presents certain challenges due to its challenging machinability and welding requirements, requiring specialized skills and time-consuming techniques. Furthermore, the unique properties and specialized manufacturing processes of Inconel contribute to its higher cost as a raw material.

Frequently Asked Questions

Which Audi R8 does the Kline Innovation Valvetronic Exhaust System for the R8 GT fit? This system fits the Type-42 Audi R8 GT (2012) with the 5.2L V10 engine. It is specific to the R8 GT model, so it is not the same system as Kline’s pre-facelift V8 R8 exhaust. Because the R8 GT was a limited single-year model, confirm your car is the Type-42 R8 GT before ordering to ensure correct fitment.
What is the difference between the Stainless Steel and Inconel versions? The system comes in two materials. The 304 stainless steel version weighs around 19.5 kilograms and is the more affordable, durable industry-standard option. The F1-grade Inconel 625 version weighs approximately 9.0 kilograms, using aerospace-grade thin-wall construction for a substantial weight saving and a more vibrant note. Inconel carries a higher price reflecting its raw cost and specialized machining and welding.
How much power does the Kline R8 GT exhaust add, and how does the valve system work? Kline states a gain of 21 horsepower and 27 Nm. All cross sections are enlarged approximately 10% over stock to balance torque and power, with fully unrestricted flow through Kline’s signature x-pipe when the valves open. The valves are actuated by the car’s factory vacuum system and can also be controlled by Kline’s wireless remote Inconel Button kit, sold separately.
How does the exhaust sound when cruising versus at high revs? The valvetronic design lets the R8 GT cruise quietly with the valves closed, routing gases through chambers and acoustic segments that eliminate cabin drone and resonance. When the valves open, flow becomes completely unrestricted through the x-pipe geometry, delivering Kline’s high-pitched, dynamically resonant roar at high revs. This gives refined daily manners with a raw character on demand.
Is this exhaust street legal, and can it be returned? This item and any similar items are not CARB approved and are not for sale in California or other states requiring CARB certification. No assessment is made regarding EPA anti-tampering compliance; check with local enforcement officials regarding legality where you live. As a built-to-order special-order item, confirm your material choice and R8 GT fitment before ordering.
