I have 2012 Sierra Denali AWD, trying to put my stock headers and Y-pipe back, But something doesn't seem right between the header and y-pipe, looks to be a gap...see pictures below. Please help guys

You're probably missing a donut gasket that fits in the exhaust manifold outlet

If that is the passenger side, I believe that you need a donut gasket to go in there. And I believe that the driver side just takes a metal ring.
