Catalytic Converters

I'm gonna be ordering a header rather soon from NOPI online and i'd like to order anything else useful (that i can afford :rolleyes: ) at the same time. I've heard that the factory catalytic converters are pretty good, but a found a magnaflow hi-flow cat for under $100, and i'm wondering if this is a deal. My car, 1995 Prelude Si, has almost 103,000 miles on it, does a cat perform for a long time cause i've also heard about people saying that theirs were clogged. Any help appreciated, thanks.

I've heard good things about carsound.

Thanks, i've actually never heard of Carsound but it looks good so far

If I'm not mistaken, Carsound and Magnaflow are the same company. And besides that, that Carsound cat looks exactly like my Magnaflow cat.
