i have a 2020 Yukon with the 5.3L. Has anyone done the resonator and flapper valve delete but kept the factory muffler. I did it on my 2014 Tahoe with 5.3 and it gave me that subtle extra sound i was looking for. For whatever reason the new trucks exhaust looks slightly different but then again i can't remember the last time i ever climbed under my 2014 when i had. Just looking for a very mild sound enhancement.
