THE SOUND

High flow catalysts, or decats, open the volume up significantly, while our signature 1D CLR tight radius x pipe raises the pitch to where a supercar should be. Crafted from premium F1 grade, Inconel 625 superalloy, not only vastly reducing weight, but also adds that special tonal quality to the McLaren that can only be achieved by Kline Inconel range.

Available in Decat for optimum sound and performance, or a choice of 100 or 200 cell high flow sports cats. The cats section is modular, allowing the cats to be swapped with decat very rapidly, depending on intended use.

Great bang for your buck!
Swapped out my old impeller and this helped fix my overheating issue. Super high quality, fit like a glove. If you know what you’re doing it’ll take you an hour tops. Super solid for the price! Fit into my 1990 alpha one gen 1 outdrive on my 4.3 Mercruiser.
