Bolts marked 88 not 8.8 Stretched and parted at threads-blocker.
Graded studs for exhaust would have been Nice, GDP kit.
EZ-LYNK No Problem.
Thanks, don

Exhaust system.

If I had to complain about anything it would be that instructions while a little vague on where to cut it.
But if you mark it up and pay attention to what you're doing everything falls right into place.
The system fits terrific like it was made for the truck from the factory so I would have to say it's a very good product. Also sounds great with the muffler not much different than the factory exhaust and that's what I wanted a quiet truck not a lot of noise.

Great quality and sounds amazing

Makes your diesel sound like a true diesel! Great fit and finish. I installed the exhaust with the muffler and love the way it sounds. Fast shipping and great customer service!
