    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.
