Aftermarket Vs. OEM

[kcf881]

I'm going to be installing a Y-pipe on my Maxima very soon. Since the car has about 165k miles on it I thought maybe I'd replace the cat as well. However the stock cat has given me no troubleat all. This raises two questions; should I bother replacing what may be a perfectly good but hi milage cat? If so what should I replace it with, an OEM cat or an aftermarket hi flow? This car is still a daily driver so emissions are a concern. This is a 91 se 5spd. I await your advice.

Leave the stock cat, no advantages with going with aftermarket. BTW, an oem, dealer cat converter is somewhere around $800.

I believe I paid $80 for my cat already installed with 2 years/25,000 warranty. I'm not looking for performance so I dont care..its a 91 dude...do you really need something incredibly oem?

Leave the cat alone

Leave it, but if you have to change it, go aftermarket. It will be cheaper and you still should pass emissions.
