Sierra 2500 8-cyl

When traveling merging on I-70 outside of london Ohio my truck started making very loud exhaust sound. After inspection found that driver side and passenger side rear exhaust manifold bolts where broke off allowing unfiltered exhaust to pass. If leak would have been too bad the high temperature of the exhaust could potentially cause a fire inside the engine compartment. The exhaust also broke welds off the exhaust causing the exhaust to fall the break is where the H-pipe come together.
