My buddy picked up a modified Hellcat Challenger last last year, so we got together to have some fun and see whos car sounds better. My 2010 Shelby GT500 has American Racing 1 7/8ths headers/Catted X and a 3" MBRP Race Series cat back. The Hellcat has long tube headers/ catless mid pipe and a catback, but he is unsure of the brands. ( The previous owner died from Covid ).
Both cars also have some serious power upgrades as well.
Let me know which exhaust system you like better.
