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, Jason
Hello, I got a chance to tour Fort Wayne Assembly yesterday with GM's Tim Herrick, Executive Chief Engineer for Chevy and GMC full-size trucks. I thought this group might be interested in my video about it. Thanks.
