2010 Silverado Exhaust Or Vaccum Leak?

[alkaspeltzar]

2010, 5.3L Silverado 4x4 ~26,000miles

 

hey guys, the reason I am asking is becuase when driving, especially pulling, I can hear what reminds me of a vaccum leak or very faint exhaust leak.

 

I have had this pesky sounds for about 10,000 miles now. I have looked at the exhaust manifold and connections in the exhaust. I see no signs of leaking. Yet the noise still persists. Lookin for anyone with similar issues or problems that might have a suggestion.

 

PS: Could be noise from enigne in general. I have check rubber boots in firewall, but that doesn't mean i am missing something.

 

Please let me know if you can help!

Why else would you buy a new vehicle? Use that warranty!
