How do I tell?

So the tag on my Jeep says it was made in 1/2000. The exhaust system cat back changed on 1/24/2000. Is there any way to know if it was made before or after that date?

Probably something in the vin that would be a code in the Toledo plant when it was made.

Please re-state your question. I'm confused.

I think he wants to know if his was built before 1/24/00 because the cat-back is different after that date? I'm not sure though.

That is correct, but the sticker inside the door only states that it was built in 1-00 or January of 2000. The exhaust changed on 1-24-2000. I am wondering if I can find out if my Jeep was built before or after that date somehow.

I got a build sheet from Chrysler but unfortunately it does not show the actual build date. What is different about the exhaust that makes you curious? Is it something you could ask someone with an earlier TJ to take a pic of to compare it to yours?

There are two different part numbers depending if it was made before 1/24/00 or after. It may be a diameter difference, but I can't confirm that yet. One sight has the diameter at 2.25" and another has it at 2.5". I am thinking it is inner diameter, but not sure.

I figured it out. I pulled the actual part number off the stock muffler and did an internet search and it is an after 1/24/00 production muffler. The difference between before and after is the diameter of the pipe.
