Standard catalyst (300 cells)

This standard catalyst (300 cells - HJS) fits on:

> All 964 Turbos

This version is equipped with a standard 300cc metallic catalyst - KJS. It therefore allows the original catalyst to be replaced without changing the performance. There is no gain in power with this catalyst. The original additional air intake has been removed because it takes horsepower with its belt for no service rendered. For the record, this system was made by Porsche to "inject" fresh air from outside into the muffler to artificially lean the exhaust gas mixture at the outlet.


We also have in our range:
> A 100cc sports catalyzed version - (Reference: SCA 964T 2 2)
> A bypass version with muffler - (Reference: SCA 964T 2 3 S)

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.

This catalyst is mounted directly between the turbo and the final 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.

Using a lift is essential. Recovering the original lambda sensor is not easy; plan to replace it or purchase a new one if necessary.

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 gaskets, stainless steel screws, all-stainless steel lock nuts and high-temperature copper grease.
