Nope. Pretty sure the cats on the hellcat are the same or very similar as the 5.7 and 392 just with a different diameter. I have Catless, it sounds cool but I'd get cats if I did it again.

Yup the 6.2 and 6.4 seem to use the same part number.

My guess would be you get a couple of ponies.

IMO the cats on the challengers are pretty high flowing cats compared to what I had on my Infiniti back in the day.
