    300 5.7L Mid-muffler swap

    Anyone done a mid-muffler swap and if so what did you use on your 5.7?! How do you like it?
    Looking for ideas to do to mine. Don't want it wild, just a nice rumble with a bit of noise at wot
    Thinking of either a bullet swap for the mids, or a 3-chambered swap for them so far...

    Yah, I've heard lots of cat-backs and reso deletes, but wanted to see if anyone has done mid-muffler swap and how it went. I wanted to leave the reso's so I don't have any drone...

    Lol! I took the resonators off first. Gave it a nice low growl, but it wasn't loud enough. So I went with the Flowmasters. It's not obnoxious, but you can hear me coming. It has a drone, but it doesn't bother me. I like the sound.

    I appreciate the info, but wanted more info on the just mid-muffler swap. I've found lots of info on reso deletes, but I don't want it that loud and don't want drone if possible, thanks for the info.

    I have a Dynomax catback on the charger, no resonators. Sounds great and I don't have any drone.

    I've seen tons and tons with reso deletes, none seem to have what I want.

    When my suitcase started rattling inside, I had it replaced with 2 SS oval Magnaflows. I don't know what model they were but they are just a tiny bit louder than stock.

    then I decided I wanted more noise so I had my resos removed. Sounded great when accelerating but the drone was too much at part throttle cruising so the shop installed two small bullet resos. They reduced the good sound and did nothing for the drone. So I had stock resos reinstalled and decided I would stay in the stealth mode. If I did it over again, I would put some louder mufflers on in place of the suitcase.

    Thanks 2005rtmag, sounds exactly like what I'm trying to do. I'm wondering if a longer bullet style or or maybe a super 10 single chamber would work well without being too loud with the stock resos :/
