Description
We are proud to have partnered with the Romanian supercar exhaust boutique; Kline Innovation, to bring you their range of unique exhaust systems. This system is for the following:
Kline Innovation Stainless Steel Exhaust System to fit R35 Nissan GTR – Includes the Rear & Centre Sections
- Rear Section Exhaust System & Centre Section (Utilises standard tail pipes - Carbon Fibre one can be bought separately)
- Exhaust Tube Diameter: 89mm
- Exhaust Material: Stainless Steel T304
- Application: Suitable for R35 Nissan GTR
Supercar quick, hyper car capable, the GTR will dominate many of the revered supercar pedigrees. The 3.8l twin turbo V6, a marvel of modern engineering, has enormous potential beyond the factory 475hp. Of course, we at Kline were eager to build the ultimate GTR exhaust. The criteria, flexibility on design and cross sections to tune perfectly with your desired power, whether you’re building a 1400hp monster, or 650hp daily driver, Kline can offer the best in materials and expertise to realise your dream.
The Innovation
The 3.8l V6 engine being mounted at the front of the GTR, designing and building an exhaust with a high standard of sound and performance might be considered a fairly easy task. However, we at Kline take perfection very seriously, and as a result felt we had to take our GTR exhaust to a whole new level. How could we achieve this? With a combination of elegant design, uncompromising materials, acoustic, and fluid dynamic modelling.
The Sound
Enlarging and simplifying the rear silencer section, we were able to essentially consolidate the volume of the 3-silencer factory setup, into a more efficient twin rear silencer design, further lightening the setup. the rear silencers have been volumetrically tuned towards removing bass drone at cruising speeds, while giving a rich aggressive vocal at high rpms. The sound is accentuated in the treble frequencies, giving a higher pitched more aggressive sound when you need it.
ABOUT KLINE INNOVATION
At Kline we take exhaust design very seriously, you as the customer desire a product without compromise, and we therefore take an unequalled approach to design and manufacture.
MATERIALS
Here at Kline Innovation, we believe in the absolute best materials for every application, chosen scientifically by the material’s natural properties. Titanium/Inconel/Carbon fibre exhaust boutique, of course we also offer 304 stainless steel as an alternative on our complete range. Every material has its own unique properties, and perfect application based on weight, strength, heat resistance, and chemical stability. And of course, we at Kline strive to craft some of the world’s best lightweight exhausts utilising every innovation possible!
The following is a brief overview and explanation of the different materials we use, properties, and functions.
INCONEL
Inconel 625, as used in the aerospace industry where extremely durable and heat withstanding components are required, for example for the exhaust turbine blades in high performance jet engines. Inconel is also used for the manufacture of formula one exhausts and has also been used by some manufacturers on hyper car projects such as McLaren P1, Aston Martin 177, where lightness is a factor, and exhaust temperatures regularly exceed 1000c.
The basic properties of Inconel are characterised by extremely high tensile strength, and extreme thermo chemical stability. Because of the high tensile strength of Inconel (roughly the same strength to weight ratio as titanium), very thin sidewall material can be used, while still maintaining structural integrity, resulting in very lightweight components that will not fatigue over time. The main drawbacks to using Inconel, is that it’s extremely difficult to machine and weld, and requires high skill and time-consuming processes. It's also extremely expensive as a raw material.
TITANIUM
Titanium in its varying grades is commonly used in a variety of applications where strength to weight ratio is paramount. Very high tensile strength and low density mean that very light and strong components can be manufactured easily. Titanium is also relatively easy to machine and weld using standard engineering approaches. The main disadvantages to titanium, are the cost of material and that prolonged heat exposure exceeding 600c causes oxidation of the material, resulting in brittle components and potential breakages. For this reason, titanium is best suited to cooler applications where strength and lightness is a factor.
CARBON FIBRE
Carbon fibre reinforced polymer has an extremely high tensile strength to weight ratio, surpassing that of all metals. Extremely lightweight components can be moulded to almost any shape. The main drawbacks to carbon fibre being; the material cost, the fatigue endurance limit is hard to define (the material can break unexpectedly), and the lack of prolonged heat resistance due to the polymer binding agent.
STAINLESS 304
Stainless steel 304 grade has become the industry standard for exhaust manufacture. Moderate strength, thermo chemical stability, inexpensive, and easy to manufacture, 304 stainless can be used to build relatively inexpensive exhausts to a high standard of functionality and durability. The main drawback to stainless steel is the weight. Roughly the same density of steel, but reduced tensile strength, building high performance exhaust components from stainless can be limiting. Also, from the perspective of sound, the thick sidewall required from stainless, can produce a slightly dull lacklustre sounding exhaust note when compared to the previously mentioned materials!
