Yesterday on the way back from the Jemez I had a small problem right about the time we hit 550 and 528. The day before I had developed a rattle that sounded like it was coming from the exhaust. Since I've had the welds on the muffler come apart before I figured it was the same problem. NOT!
When we made the turn onto 528 I noticed a new sound coming from under the truck that varied with load. I also noticed I didn't have any power. This is why.... That is a chunk of my catalytic converter in the pipe between the muffler and the cat. The new sound was exhaust blowing out the header flange. The back pressure blew out the gasket.
The result is a new cat and muffler.
