991-2 200 cell Sport cat upgrade
for 991 in Exhaust
This modification involves the removal of the original 400 cell catalytic inserts. They are replaced by high flow , HD sport cats with 200 cells which are especially designed for the DFI engines.
The housing is closed again by TIG welding, just like the original welding.
This modification is done in our shop.
The result is a 15HP and 15Nm torque increase and a louder and deeper sound.
The car will still pass EU emissions tests and there are no Check Engine Lights.
The sport cat upgrade is sold on a core exchange base or we can modify your manifolds.
The cat elements are made by HJS.
