After TSB 18-NA-355 Was Performed

2018, 2SS Camaro with K&N cold air intake, flowmaster american thunderaxle back exhaust and AFM range finder. I just had the Transmission flush TSB 18-NA-355 performed today.

I swear my engine and exhaust sound noticeably quieter after the flush. Has anyone else experienced this?
