Sport Cat Upgrade
for 993 in Exhaust
This is a modification of the original catalytic convertors to 100 or 200 cell.
The original cats inserts are removed and replaced by high flow sport cats of 100 or 200 cells. The housing is closed again by TIG welding, just like the original welding and therefore invisible to see from the outside.
This modification is done in our shop.
The result is a HP and torque increase and a louder sound.
The cat elements are made by HJS.
