First question: how big is the chance that you even need new ones when you take off the X-pipe?
Then, which one for the 4.2 automatic? Lt. Etka have ABH and PT the same X-pipe (441253101Q), but different sealing rings.
The matching X-pipe picture would be the one of the PT for the switch and the sealing ring again.

It doesn't seem to fit together. What do I need if anything?
