997-2 DFI Exchange Sport Cats
for 997 in Exhaust
The 4 original catalytic inserts are removed and replaced by high flow , HD sport cats with 200 cells which are especially designed for the 997-2 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 10 HP and 10Nm 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 simply modify your cats.
The cat elements are made by HJS.
