Speak To An Expert on 346-514-5073

Product Details

The Porsche 718 GT4 RS, revered as the pinnacle of track orientated weaponry, at 500 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!

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, opens 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 complement the exhaust perfectly.

Performance

Replacing the OPF with a specially designed silencer, removes the most restrictive component, without causing drone 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.
