Kline Innovation Porsche 991 GT3/GT3RS Manifolds

Capitalizing on a formidable heritage of race bred 911’s. Upwards of 475 hp, and a 9000rpm redline, the Kline Innovation Porsche 991 GT3/GT3RS Manifolds will  make the exhaust scream like a racecar should! 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.

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.

The Kline Innovation Porsche 991 GT3/GT3RS Manifolds biggest 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.
