Hey All,


I just bought a 2023 Chevy Silverado 1500 LT 3.0L LZ0 Duramax - Brand new from the dealership about a month ago.


I have done quite a bit of exterior work but want to begin some performance modifications.


My question is...  Do the 2023 Chevy Silverado 1500 LT 3.0L LZ0 Duramax have an exaustt flapper valve?


I was doing some research and was going to get under my truck to modify the flapper valve/muffler delete to stay open, but I couldn't see or find it.


I also saw some people who got some muffler tape to tape over the 3 "mesh like screens"/resonator deletes but could not find those either.


Any/All help would be greatly appreciated.


Thanks in advance,
