Header Swap

khshockey44 · June 2, 2016

I had a 2010 GMC Sierra with the 5.3 that I put some direct replacement headers on. When I traded in for my 2013 I pulled them off and replaced the manifolds and they have been sitting in the garage ever since. I picked up a 2016 GMC Sierra All Terrain the other day and was curious if these will bolt up in place of my stock exhaust manifolds, or if they would have to be modified to fit.

They wont even fit at all, 2 completely different motors. The 2010 used the LSx series engines, the 2014+ uses the LTx series engines. Other than 2 bolts inside the engine there are not any parts shared by the engine families.

And for 25 extra points the two bolts are?......
