So I added 2 flow master super 44 to my 2012 Chrysler 300 with the 5.7 and it’s so quiet. I didn’t want to do a resonator delete so that’s what’s Holding back sound. My next question is has anyone put scat pack resonators on their 300? I bought some and they are much smaller than the big o suite case. Would it make a difference in noise? I want it a little louder

I went with straight pipes along with a cheap glasspack to replace the mid muffler. It's nice and loud but still enjoyable for daily driving. Honestly I would like it a bit louder but when it was straight piped there was no back pressure and the low end torque was crap. I have a few clips of my car on the channel if you want to check out.

I'm running Super 10's with hollowed CATs, sounds louder but not as furiouscious like a Merc C63 decat. I think on ours it's a bit hard to strike the right balance. I also have Super 40's, which I like very much, it's less louder but has more bass tones which can heard heard for miles. Just my experience

Do you still have your resonators? Or removed them?

I was told you only have to have cats in Cali - That you can run straight pipes just fine. I think I was misinformed. :(

I'm going to assume that you didn't add the Flowmasters, you replaced your factory mid-mufflers with them. If that's the case, you won't notice much if any difference because your factory mufflers aren't very restrictive to begin with.

I wouldn't delete the resonators either, for many reasons. But you can certainly try a lower-restriction resonator. Look for something from an SRT or 6.4. These are pretty much straight through designs (check before buying, make sure you can feed a stiff wire through end-to-end). You'll need adapters for the front of the resonators, but that's not a big deal.

Personally, I decided not to go this route because the one or two folks who've posted online about a swap like this complain of drone. But that doesn't really make sense to me, because SRTs don't drone. It might sound funny in 4-cylinder mode, though.

If it's in your budget, consider a Solo Performance catback. I think that'll give you the sound you want, and they are designed with an adjustable J-pipe to eliminate drone. Plus they're all stainless steel, like the factory exhaust.
