just recently put my stock back on, i always remembered the stock exhaust being nice and tight. when i tap it it moves around. what could be the issue here?

 

did you install all the hangers back most aftermarket systems do away with the extra hangers for the mufflers. Then again it could be that from in stall and removal. With the factory exhaust before any removal is is put in and not toched so is alought tighter.

 

if u can simply touch it n it moves i vote it to be the middle hanger u forgot to put on...or your rubber hangers are severely worn

 

I had the same problem.
