Welcome to the forum!
Welcome. My 2020 300s 5.7 has an x-pipe and a crossover at the rear of the mufflers stock - maximum efficiency was achieved without any 'noise'. Was your car any different?Good afternoon,
Bought a 2018 300C with the 5.7 as my daily to replace my 2010 Ram. I’m trying my hardest to not scratch the modify-itch, but I did the basics, namely the exhaust. Lately, though, I have been thinking about changing a few things, such as making this boat handle a bit better andgetting rid of the chrome. Maybe someone can talk me out of it…
I want to keep it as much of a “daily” as possible for the comfort of my 1 year old son, which was the main reason for the purchase. I also normally autocross my 1974 Camaro, and I think it would be fun to try it out in the 300. Hell, I’d love to get it up to Laguna Seca.
I’ll start a few threads related to the questions I have. Here are a few pictures of the rides.

My car....
Appears to be an aftermarket exhaust setup. No images of my factory setup at the moment unfortunately. Truly impressed with my factory setup. Hoping someone else can provide some insight....Mine has the factory “x-pipe”, but no other crossover toward the rear. View attachment 21829
This was before I put the full-size Ultra-Flo mufflers on.
I should have said this was before the UltraFlow Mufflers, but after I changed up the factory exhaust quite a bit. The setup in the picture sounded awesome, but the drone was unbearable.Appears to be an aftermarket exhaust setup. No images of my factory setup at the moment unfortunately.

Next time my 300 is in the air, I'll get images of the exhaust system - truly impressed. A proper factory exhaust without the noise. The current Eagle 5.7L motor is available in multiple variations from 363hp to 395hp (advertised net), with and without MDS and with six reported available cam profiles, depending on the application.I should have said this was before the UltraFlow Mufflers, but after I changed up the factory exhaust quite a bit.
