Flowmaster 50 delta flow opinions

[Graphite Silverado 2018]

So ive tried many many different configurations. Currently i run a flowmaster flowfx si/so. All cats in place, res, and flapper removed. Sounds decent but not what im looking for. I used to have a super 44 on it si/so, its was awsome but too much cab noise. Ive tried borla, magnaflow, corsa, and carven. Im loyal to flowmaster been using them for 25 yrs now. I was thinking the 50 delta flow si/so would be perfect. Just enough growl and calm inside the cab. The super 50 is not deep enough imo. Anyone have the 50 delta flow muffler or similar? I still have my afm as well, not really planning to disable it. How is the cab noise? How is the exterior?
