Hey guys, i got a 2010 silverado, 5.3Liter, 26,000miles

I have faint exhaust noise on the drivers side, coming near the pedals. ANyone else experiencing this? Could anything in the exhaust be causing this or is there anything in the truck that might be allowing the noise through?

Sounds like the connection between the exhaust manifold and y-pipe is leaking barely. But everything looks tight and clean, no mods, just trying to find this noise.
