Rattling Cat

[tommy583]

Ok 1998 2.5 base with 2000 S crios mod factory muffler, factory exhaust manifolds (with no cats) and factory pipes with cats in them. One of my cats is starting to rattle. I know it's not the heat shield because I removed them.

So I think I have a few choices to cure this problem. First I could get a used cat pipe from Woody. Or second I could get some Ebay headers and pipes with high flow cats. Just replacing the cat with a used one would be the easiest and cheapest for sure, but for less than $500 I could get the headers and cat pipes.

Does anyone on this forum run a 2.5 with headers and high flow cats? If so I'd like to hear your thoughts. And yes I did a search and read about it for hours, but I didn't really find one about the set up I plan on going with.

So to sum it all up. 2.5 liter with headers, high flow cats and factory S muffler with crios mod. What do you think? Any worthwhile performance gains to be had? I'm sure it would sound different, maybe better.
