For some reason I had in my head that removing the third cat would throw codes, but I guess there are no O2 sensors behind that cat so there is no way for it to throw anything.
In all honesty, I would probably like my old banks muffler back with a cat delete. The banks with the cat was just barely loud enough. I'm considering just buying a bunch of adapters and a cheap muffler and trying some combinations around for a weekend. A straight pipe might be fun for a week... but there is no way I'm going to blow my ears out for much longer than that.
When I first got in the Jeep after my new exhaust, I started grinding the starter with the engine already running because I couldn't tell it was on
