I CAN RELATE. I caught our GMC floor on fire. And the exhaust system was 4 months old. On interstate 88 West of Chicago. 11 PM, and at 22 degrees out. Exhaust was getting a little louder. Pulled into a rest area. Checked all the SS band clamps. Used a 9/19 socket to make sure all were tight. Pipes looked good. And the mufflers were still shinny. Checked the new gaskets at the exhaust manifolds. Fine. About 30 more miles down the road. A trucker came by with his interior dome light on. With his finger pointing down for me. I was just about 600 ft from an off ramp. Went up the ramp. I had a floor fire on my hands. The top of the new muffler had cracked open. The 78's have an aluminum skin on the bottom side. That aluminum never burned thru. But transferred enough heat to start the floor on fire. I now have a heat shield above the mufflers. That has a 1" air gap above that shield. Just about burned up a GMC a second time. It can happen to YOU TOO. Bob Dunahugh 78 Royale
