Let the rig warm up and went out to load up a buddy's truck. Didn't leave mine running while we winched his rig up (blew the driveshaft) thought that it would still be warm 35min later.
Started up a 20deg incline and all the sudden had a lurch and sounded like my engine was going to come through the cab.
Pulled over and found my exhaust manifold in 3 pieces!!!!!
AAARRRGGGHH!!
