Utilizing the same “superalloy” found in Formula One exhausts, Kline Innovation offers their systems for the Porsche 911 Turbo and Turbo S in Inconel 625 (as well as the more traditional 304 stainless steel).

For this 2019 Carrara White Turbo S cabriolet, it’s Inconel all the way through. In addition to the turbo-back system that includes higher-flowing cats and Kline’s signature x-pipe design, a set of Kline headers replace the factory manifolds.

With its high nickel content, the Inconel system features superior heat resistance and drastically cuts weight over the factory exhaust, as well as the 304 stainless version, where it is nearly half the weight (7.5kg vs 14kg for the turbo back system, and 2.9kg vs 6kg for the headers).

The result is a modest horsepower gain over stock (Kline claims 16 hp with the 200 cell cats), but this car benefited from additional calibration for a dramatic power increases for the Turbo S, supported by higher-flow intercoolers.

Sound is greatly improved, as the Turbo and Turbo S is notoriously quiet in stock trim.

Revving in Park doesn’t do the system justice. Under acceleration is where it’s at.
