Vibration with new 3" downpipe (solved)

Hey guys I just purchased a new 3" downpipe with a straight 4" exhaust and after I installed it I noticed a vibration at low engine speeds (below 1000 RPM). It was driving me nuts, so I inspected the exhaust and noticed that the exhaust clamp on the down pipe was was touching the transmisstion. Once I took the exhaust appart and reinstalled it while making sure NOTHING was touching the exhaust pipe, the vibration was gone!

One more thing, if you are replacing the stock body mount bushings on your truck, you can gain a little more clearance between the Down Pipe and the body by pushing the cab slightly back before you tighten all the cab mount bushing bolts down. This is what I did and now I can fit my whole hand between the cab and the down pipe!!

How close is the cab to the bed or box on your PSD after you moved it?Glad you got fixed
