Has anyone changed the muffler out on the 2014 Sierra, 5.3.. I want to do, I want a low rumble without changing the whole exhaust system. Any recommendations, and will there be a problem with dreaded drone or issues with the v4 mode that will make this pointless. I've looked on the net with no clear answers. Someone recommended a cheap thrush system.. Any experience? Help appreciated
