hey peeps,
Just wondering if a defective or stuffed up CAT can affect performance in a car? Also when upgrading exhaust is it worth it to upgrade the CAT?
cheers

Most definitely a defective/non-functional catalytic converter will attribute to some power loss.
With respect to the AP1/2, the OE catalytic converter is already very good in terms of flow and isn't required to be replaced by a more substandard local made product when changing a catback exhaust. (DC2R owners would select the OE AP1/2 cat as an ideal upgrade just like their JDM exhaust manifold).
To extract maximum gains in this department, it'd be optimal to run a test pipe matched with a N1 single output catback. I'm sure you already know that. ;)
in my friends commordore the cat was stuffed
he then pgraded to a high flow cat instead of standard and noticed better performance and fule consumption
sounded better as well
