I got a p0420 last week while cruise control on at about 60 mph for 20 miles or so. Looked it up on here. reset it. didn't get it again. Today I was on a trail coming back down the mountain. Hear what sounded like pop corn popping from cat converter area. Then some nice bumps and rig sounds like a race car. Get out to check it and just at the y in exhaust is broken in two. The two pipes have broken off from the one pipe that leads to cat converters. While driving back i got a p0170 code. did a search and dont see anyone talking about a broken exhaust. What do yall think? Obviously I need to get the exhaust welded back together.
