997-1 Exchange Sport Cats
for 997 in Exhaust
The 4 original catalytic inserts are removed and replaced by high flow sport cats with 200 cells. 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.
This is an excellent and cost effective solution for cats that cause CEL 0420 and 0430 due to broken elements.
The used cats are made by HJS.
