When developing the Porsche Sound exhaust system, no attention was paid to price - only to quality, reliability and the fact that the exhaust should deliver more power as discreetly as possible.

The Porsche Sound exhaust system is made entirely of stainless steel; the visible parts of the muffler and the outlets are polished. All unpolished parts have been sand-blasted to avoid heat build-up. Extensive testing has shown that an exhaust system that has not been sand-blasted is on average 24% hotter than a fully polished exhaust. The crankcase temperature (directly behind the pulley) was 0.5 percent higher than that of the fully polished exhaust. The most important measurement, however, was the temperature at the exhaust ports, which was on average 17% higher. It is known that stainless steel can dissipate less heat than ordinary steel, and when it is polished this can be fatal for the valves.

The strength is found in the rear muffler, which is based on the Type 4; the flange connection and the distance from one flange to the other are exactly the same. In terms of fitting, the Porsche Sound mufflers could be fitted directly onto a Type 4 engine, provided the outlets are not in the way.

To improve flow, a 38 mm pipe was used, and the heat exchangers can no longer be used. A solid flange connection with 8 mm thick flanges was chosen, instead of slip tubes that can cause leaks, which would adversely affect performance.

The name comes from the specific Porsche sound.

The exhaust system is supplied complete with all the required fastening hardware and gaskets.
