Well I am still not seeing everything I need to see. Would have liked to see the pipe that is connected to that Y pipe to the cat.
But now you are saying things are welded? Sounds not stock.
I believe factory stock would the Y pipe would be one piece all the way to the cat.
Aftermarket stock the Y pipe would be bolted to a pipe which would bolt to the front of the cat.
But that would be a build date after 1/20/00.
You saying it is slip on leads me to believe it is before.
Which makes things tricky.
Also you did not post the build date.

 

Build date is 10/99 so you were right. You may be right that it is slip on but there are no clamps or flanges.

 

I was afraid of that. Early, before 1/20/00, '00's are weird.
Still wondering if the Y pipe is one pipe all the way to the cat.

 

One piece all the way. I’ve found many weird things with this Jeep so far

 

Made a little storage pocket for the console lid. Nice spot to keep stuff.

 

See this is why I love the forum.
I think I am going to have to steal that idea.
Thinking perfect place for the registration and insurance card.
Beat leaning over from the driver's seat trying to fish it out of the glove box.
Or digging it out of the mess in the console.

 

A mesh pocket from an old gym bag is all you need! Just undo the screws and tuck it under there

 

Here’s a couple of interior photos of my sunroof. It’s not stock but the install job is pretty good. Having a functioning sunroof that doesn’t leak is pretty cool on an XJ

 

Rolled over 150 today. I’ve owned it since 128 so I’ve put on a good amount in 4 years.
