Just purchased a 2019 at4 with 6.2l. Looking for some exhaust ideas. I don’t want to be drowned out like my 2017 Silverado 5.3 cat back Corsa cat back. I loved the sound but highway speed or down shift the cab was to loud to my liking. I just want alittle rumble to the 6.2! Would like to just replace the muffler to get alitte rumble and be done. Any recommendations or comments much appreciated.
