Applying our usual formula, F1 grade Inconel 625, tuned cross sections, and perfect X pipe geometry, we were able to craft an exhaust that not only has the perfect sound, but is lightweight, durable, and performs to the highest expectations.
The Sound:
Starting at the manifolds, replacing the stock cats for our 100 cell, or long tube catless Inconel headers opens up the sound significantly. The gases are then passed through one of 2 channels. On valve closed, the gases pass through our harmonically tuned, and internally ceramic insulated wing silencers to remove unwanted drone during highway cruising, and into the center muffler, and finally our trademark 1D CLR x pipe, this setup keeps the car very civilised when you want it to be. On valve open The wing and center silencers are completely bypassed, allowing the gasses to pass freely through the exhaust system. The geometry of the Kline 1D CLR X pipe raises the pitch of the exhaust significantly into a raucous, yet beautiful, incindiary scream, without causing any restriction to the gas transit. The material Inconel 625 also has a unique sound, further enhancing the natural charachteristic sound of the kline system. The sidewall is very thin, and resonates to produce an even higher pitched scream at high revs.
Performance:
The largest performance gain comes from replacing the catalysts in the stock headers. The Kline headers and full system are designed to work in conjunction with eachother for optimum performance and sound. The Kline system and headers are available in 2 options, 100 cpsi catalysts producing a largest gain of 18 hp and 27nm, or decat long tube headers producing a largest gain of 20hp and 31nm.
