Ok, so I need to replace my cats. I looked around and the dealer wants $400 something per cat, which is insane. I found a place that manufactures a diret fit for $250.

Here's the kicker: I found THIS link.

If you scroll down a little bit you'll find that some cats for the X they sell for around $200 something and there's one they say fits 2000-2004 that costs $60 some bucks.

What gives? Anyone know why there's such a price difference?

I'm suspecing that those may not be a direct fit, but since the X's cats are right after the manifolds they can't be cut with a generic cat welded back on to the pipe, right?

I need a little bit more insight on this...

Thanks.

Couldn't you get an adapter that would clamp on or weld on to the cat?

Here's what I plan on putting on mine. A lot less expensive than Nissan whats to charge.

Cats

There are two cats on the Xterra, aren't there? Thats what I would want too, now I just need a pipe bender and some stainless steel and I'm good to go!
Thanks for the link, Dagger!

There are two, four if you have California emissions as I have, but I will be going to federal emissions standards.
