Oil leak after exhaust upgrade

[Kmack]

Hi All, happy new year. I was wondering if anyone had an oil / fluid leak after upgrading your exhaust? I recently upgraded my ‘23 Tahoe with the borla exhaust sold by Chevy. I noticed a couple of puddles under my truck. I left a VM with the Chevy dealer who installed the exhaust last week. Curious if anyone had a similar issue? The puddles are located towards the back half of the truck. This is a Z71 with 6.2L.

Are you sure it's oil? There was an extensive thread about exhaust condensation dripping from the joints in this thread - https://www.tahoeyukonforum.com/threads/22-yukon-exhaust-leak.138238/

Yes, you are right. It's not oil, its carbon buildout from the previous exhaust that is leaking out. I took it to the dealer and thats what they said too. Thank you!
