To start, shortly after I bought my truck I had to bring it back for work that had to do exhaust. I assume they checked extensively for exhaust leaks and other things while they were searching for the issue(10 days), but anyways. The issue is around the exhaust.
Sometimes while driving i hear what sounds like an exhaust leak. I dont recall ever hearing the actual engine in the cab before my ordeal. I could hear the tailpipe sounds when merging onto the freeway and accelerating, however i hear ticks around the footwell and im not sure it if is normal. I know what the direct injection ticking sounds like, and it doesnt sound like that. Does anyone else hear the engine/exhaust while just cruising in the cabin?
Before taking my truck in i had only driven it 400 miles, so i really dont have enough experience to answer my own question.
truck is a 2016 Silverado LT 5.3, everything is stock.
