I've got my exhaust off to repair my rear main seal on my 06 Rubicon and the forward 2 cats look funny. The media heights are different between them, like one is halfway down the body and the other is near the top.
In the 3000 miles that I've owned it, it has always been pretty anemic but I was getting 13mpg cruising around but now I'm down to 10 or 11 tops.
Is that a symptom of the cats heading out? I've never had any check engine lights. With 160,000 miles on it, I'm not opposed to changing them for peace of mind either.
For replacement, what O2 sensor socket should I be looking for? I plan to reuse these if I order a new exhaust.
