Hi Flow Cat

[Ronnyboy]

So I went to Magnaflow cat, but I found two of them. Sorry if I sound like an idiot, but is there a specific cat we should be using on 2002's?

Performance cat.s are rated by Gross Vehicle Weight and engine size; and spec'd by input/output pipe diameter. Magnaflow may make a direct-fit cat., but I'm not sure. If it helps, I'm using a 3" spun metal on a '98 l67 with no SES light.

(correct me if I'm wrong )

One is Cali emissions probably. What part #s did you get?

I went and looked at it again, and there was only a difference in one was universal, the other was bolt on.

I also saw that ZZP had one, is that any good?
