Ok, so I found out the nasty rattle under my truck is my cat. My mechanic said it would be smart to replace it.

So with that being said, what are some good brands of catalytic converters that would fit a truck (yes, I know I'm posting this in a car site). I'm looking for a high flow, high peformance for a good price.

And is Catco a good brand? I've found a few of them for a good price.

LMK. Thanks.
