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 24hp and 35nm.

Poor quality control… Received a used pair
Size: 12, Color: Birch Beige/Farro/Ivory, Size: 12, Color: Birch Beige/Farro/Ivory
The shoes that were delivered showed signs of wear. Not sure if this was a used pair or a display pair but this should have been caught from the beginning. I would normally return them, but will be out of the country for the next month and don’t have the time. Unacceptable quality control from the official cole haan store front.

Poor footbed but otherwise good.
Size: 10, Color: British Tan/Dark Chocolate/Natural
Comfortable. Replaced mediocre footbed that has no arch support with something else and it is now great. True to size.
