Flowmaster bottle muffs on 2014 5.7
Ain't exactly pretty but it is done! Had a local shop replace the stock suitcase muffler with these: Flowmaster 12414310 DBX Muffler - 2.25 Center IN / 2.25 Center OUT.
Kept stock resonators.
Sounds quiet at idle then sound kicks in at about 50%. I like it much more than stock.
I wish I had gone to a custom exhaust shop in the first place as these hang down a bit too far.
