I just bought a 2015 Sierra 1500 with the 6.2 engine.
I noticed that the cross over pipe, from the left side of the manifold to the main exhaust collector, is substantially "flattened".
It would appear to me that this exhaust restriction ,before the cats,would make any "freeflowing" cat-back system useless.
Any thoughts?
