Radically improve the performance and sound of your Porsche Cayenne 958 Turbo with our high-quality bypass catalytic converters. Designed to replace secondary catalytic converters, these tubes optimize exhaust flow, delivering a rich, powerful sound that's essential for significant acoustic performance.
Your engine management system remains intact: the original primary catalysts and their Lambda sensors are retained, ensuring no warning lights or malfunctions. Installation is child's play: our bypasses fit directly in place of your original parts, without any modification.
Allow approximately 2 hours for installation (a lift is recommended). For hassle-free installation, a complete mounting kit is included, including stainless steel clamps, screws, and locknuts, as well as high-temperature copper grease.

> Cayenne 958 Turbo
This version removes the secondary catalysts. The car retains the primary catalysts, which are framed by the Lambda sensors; they manage the relationship with the engine management unit. Therefore, there is no impact on engine management. Replacing the secondary catalysts with tubes allows for better flow and a better sound. This is essential if you want to achieve a significant sound, because replacing the rear muffler alone is not enough.
Our exhausts all have the original interfaces, meaning that their inlets, outlets and dimensions are consistent with the original part. They can therefore be fitted in place of the original part without any modification.
These bypass catalysts are mounted between the primary catalysts and the muffler.
The average installation time, including removal of the original exhaust, for this exhaust is 2 hours. Installation time may be faster if the exhaust to be removed is in good condition, but it may be longer if the opposite is the case.
The use of a lift is essential, as the secondary catalysts are under the car at the level of the front seats.
Tightening the nuts should always be done gradually across all the nuts.
To ensure that all our exhausts are fitted in the best possible conditions, we include in the price of this exhaust a fitting kit with clamps, stainless steel screws, all-stainless steel lock nuts and high-temperature copper grease.
