I had a "Vibrant Performance" stainless axle back installed on my 2019 2LT V6. I don't recommend removing the resonater up front because the sudden change in sound when engine auto starts will be starting. The "Vibrant Performance" is the ONLY muffler out there that will fit in place of stock rear muffler on the new Blazers. The sound is low & beefy; never too much, but you always know it's there. Sounds similar to a Magnaflow, which they don't make in this configuration. One (long side) centered inlet, two end exits 2.5" diameter piping.
I had a local shop do the install because welding is required.
