Exhausts are easy to put on and take off.

Its about an hour job, and bring your WD-40 but overall its all pretty straight forward. What people don't do is tighten after heating it up. Im one of those people.

When you install the exhaust and tighten the clamps you need to make sure they are REALLY TIGHT.

Then, you need to drive the truck around for a while. Maybe a week later, get under it again, and tighten everything again.

The heat and cool, makes the exhaust expand and contract. So it will feel tight the day you install, but will loosen shortly after and will need to be tightened again.
