Sport exhaust with valves - Porsche 957 S

This pair of exhausts is our sport version with switchable valves for the Cayenne 957S. Despite the car's excellent sound insulation, these exhausts allow you to enjoy the sound of your engine. While its sound is deep and powerful, it remains discreet with the valves closed. For a more pronounced sound, these valved exhausts should be fitted with bypass catalytic converters.

We also have the following in our product range:
A sport version without a valve - (Reference: SCA 957S 3 2)
A sport version with a valve - (Reference: SCA 957S 3 2 VT) with remote control

Our exhausts all have the original interfaces, meaning that their inlets, outlets and dimensions are identical to the original part.

These silencers are mounted directly onto the tubes at the inlet of the original silencer.

For these exhaust systems, the average installation time, including removal of the original exhaust, is 8 hours. This installation time includes the mufflers, of course, but also the air intake and electrical wiring harnesses.

The use of a vehicle lift is essential.

To ensure the best possible installation of all our exhaust systems, we include a mounting kit in the price of this exhaust. This kit includes sleeves, clamps, stainless steel screws, stainless steel lock nuts, and high-temperature copper grease. We recommend applying copper grease to the screw threads and inside the sleeves and clamps during installation.
