The Porsche Cayman 718 gt4, revered as the pinnacle of track-orientated weaponry, at 414 hp the flat 6 has the power-to-weight ratio to put in some blistering lap times. So how could we improve on this epic automobile? Add lightness, tune the sound, and add performance!
THE SOUND
Removal of the heavy chambered rear silencer and replacing it with a lightweight F1 grade Inconel 625 X pipe, and Fully bypassable lightweight Inconel silencers, sheds a significant amount of weight, as well as raising the pitch of the exhaust into a more exotic tonal range. Removal of the OPF and catalysts, and replacing them with either HJS motorsport catalysts, or De-cat pipes, open the sound up significantly, complementing and accentuating the high-pitched silencer section, into an exotic scream. The Kline innovation rear Valvetronic setup, means that the car can be driven in stealth mode with the valves closed, however, a raw unhindered sound can be achieved with valves open Addition of our beautifully crafted F1 grade Pre Preg carbon fiber exhaust tips compliments the exhaust perfectly.
PERFORMANCE
Replacing the OPF with a specially designed silencer, removes the most restrictive component, without causing drones associated with OPF removal. Replacing the stock catalysts with 100 cell HJS motorsport catalysts, or decat pipes, and correcting the subsequent A/F ratios will yield up to 20 hp.
