I installed my full set of steel skids from slee last night. I noticed that the truck has a slight vibration now. I checked all the bolts and everything is tight. I am wondering if it's the exhaust pipe. It comes very close to the belly pan like 1cm or less. No rattles or squeaks just doesn't drive as "smooth". Anyone else notice this? Any fix? I was thinking of wrapping the exhaust pipe with that heat wrap but there may not be enough room...
