Kline Innovation Exhaust System (997.1 Turbo)
Designed to fit
- 2006 - 2009 Porsche 911 Turbo
The Factory setup produces the most lackluster sound, mainly due to a series of chambers, 600 cell catalysts, and the most prominent flaw being the lack of balance between opposing banks. Replacing the stock cats for a choice of 200cpsi or de-cat increases the sound respectively. Replacing the chambered transverse rear silencer with freeflow harmonically tuned silencers enriches the sound, and the addition of Kline’s trademark 1D CLR laminar flow X pipe raises the exhaust pitch beyond the region in which bass noise is able to penetrate the cabin, while under hard throttle and high revs, a rich and raucous vocal ensues. This design was pioneered and innovated by Kline.
As a turbo forced induction flat 6, the potential for increasing performance via exhaust and software is huge. The largest gains with Kline's de-cat system are 42hp and 65nm. In conjunction with software they achieved 75hp and 102nm. With the addition of Kline equal length manifolds increases the rate of turbo spool, and the addition of an extra 12lb/ft torque, and 9hp.

About Kline Innovation
Kline Innovation is a Bucharest, Romania based exotic exhaust manufacturer who utilizes exotic materials to innovate high-end systems for Porsche, Ferrari, Lamborghini, Aston Martin, Audi, Bentley and McLaren. At Kline they take exhaust design very seriously. Consumers demand a no compromise product, and they take a no compromise approach to design and manufacture.
At Kline Innovation they believe in the absolute best materials for every application, chosen scientifically by the materials natural properties. Titanium/Inconel/Carbon fiber exhaust boutique, they also offer 304 stainless steel as an alternative on their complete range. Every material has its own unique properties, and perfect application based on weight, strength, heat resistance, and chemical stability. Kline strives to craft some of the world’s best lightweight exhausts utilizing every innovation possible!
The following is a brief overview and explanation of the different materials they use, properties, and functions.
Inconel 625 is used in the aerospace industry where extremely durable and heat withstanding components are required. As an example, Inconel is used for the exhaust turbine blades in high performance jet engines. Inconel is used for the manufacture of formula one exhausts, and has also been used by some manufacturers on hypercar projects such as the Mcalren P1, Aston Martin 177, where lightness is a factor, and exhaust temperatures regularly exceed 1800 degrees fahrenheit.
The basic properties of Inconel are characterized by extremely high tensile strength, and extreme thermos-chemical stability. Due to 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 light weight 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 a high degree of skill and involves a time consuming processes. It’s also extremely expensive as a raw material.
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, is the cost of material, and prolonged heat exposure exceeding 1100 degrees fahrenheit 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.
Stainless steel 304 grade has become the industry standard for exhaust manufacturing. It’s moderate strength, thermos-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 limited. Also from the perspective of sound, the thick sidewall required from stainless, can produce a slightly dull lackluster sounding exhaust note when compared to the previously mentioned materials!
Carbon fiber reinforced polymer has an extremely high tensile strength to weight ratio, surpassing that of all metals. Extremely light weight components can be molded to almost any shape. The main drawback to carbon fiber 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.
