Final Silencers / Replacements

CARGRAPHIC Sport rear silencer for Porsche 718 Cayman GT4 Clubsport 3,8l

The CARGRAPHIC Sport rear silencer program offers various retrofit solutions for the acoustic and visual upgrading of the original exhaust system for the Porsche 718 Cayman GT4 Clubsport with 3,8l 6-cylinder boxer engine

Absorptive silencer design: Power und Sound

All CARGRAPHIC sport silencers are manufactured according to the proven absorption principle, in which the exhaust gases pass through precisely calculated chambers and the sound is absorbed by surrounding stainless steel wool via perforated pipes. This method allows a sporty exhaust noise without obtrusive drone or resonances. Absorption silencers also offer, in combination with a continuously enlarged pipe diameter, a significantly optimised exhaust gas flow and thus a reduced exhaust back pressure..

Version TRACK / COMPETITION - For the racetrack with silenced and non silenced separated exhaust flow:

The TRACK / COMPETITION silencer, in conjunction with our 3-mode exhaust valve control, has been specially developed for use on race tracks with particularly restrictive noise limits. Both inlet pipes are separated and provide with 2,5"/63,50mm each, compared to the 55mm and 45mm standard pipes, for maximum flow and best possible reduction of the exhaust back pressure. The upper exhaust stream flows permanently through the silencer, which already reduces the fundamental tone compared to the other silencer versions. The lower exhaust stream flows (with the valve open) directly into the tailpipe, while with the valve closed the complete exhaust stream is first directed through the silencer. Due to the pipe diameter of 2.5" / 63.50mm and the special large-volume, triangular silencer design, operation with a permanently closed valve is possible even under full load.

SUPER SOUND: With the exhaust valves open, loud, as an exhaust stream 63.50mm/2.5" flows non silenced into the tailpipes.
SOUND: With exhaust valves closed 63.50mm / 2.5" silenced pipe flow through silencer.

Traditional craftsmanship supported by state-of-the-art production technology.

SS304L lightweight stainless steel, manufactured to the highest standards for the aircraft industry, provides the base for almost every CARGRAPHIC exhaust component. Each silencer and exhaust pipe is manufactured using traditional craftsmanship with the support of the latest manufacturing technology such as computer-controlled CNC bending machines, laser cutting machines or orbital welding equipment.
