Badge question

Got this Charger back in August and have loved every second of it so far, smiles per gallon and all that! I was wondering though about the SRT emblem on the grill. As far as I know, it’s a stock, bare bones 5.7L R/T. I got it from Carmax and the Carfax report said no accidents, one previous owner. My understanding is SRT is 6.1L and up. I could be wrong about that, but it also makes me wonder if the grill has been replaced or if it did actually come stock like that. Any insight would be appreciated! Hope everyone had a great Christmas and an even better new year!
