Hey guys im new to the forum this place is great!, I need a little help on a diagnosis my 04 1500 runs fine no strange sounds or smells no holes in the pipes but when I take it through inspection it fails emission becuase of to low of a exhuast reading im thinking maybe clogged cats ,bad manifold or the gasket?

 

My guess is either clogged cat or a leak. Check you around the manifold for broke bolts - common...

 

thanks hammer
