Can anyone verify this?

It seems there was a mid-year change in the 03 where the hanger for the final cat was changed.

I ordered an 03 walker y pipe with pre-cats for my 03 TJ and it seems to fit fine. I had to send the 03 Eastern/APE final cat back because the hanger was not even close to being right.

These two pieces mated by an odd size 3 bolt flange. The 04 stuff is all slip together.

Currently planning to gut my oem 3rd cat and have that flange welded on as at least a temporary fix.


If you have an 03 and are ordering new exhaust parts you might want to check to make sure you don't actually need an 04 exhaust.

I have an 04 built in Oct 2003, bought in Jan 2004 and can confirm that I have the late 04 hanger as expected.

Both images are looking from the muffler connection, but the images are clear.

00-03 hanger is low

"04"-06 hanger bracket from the transmission is high
