  1. SLP Resonator (LM1) coupled with stock resonator

    Performance Discussion/Modifications (2011 +)
    I have a 2013 Charger R/T. I bought a pair of SLP resonators, or the Loudmouth 1’s, and I am wondering if anyone here has paired them with the stock resonators, and if it helps with the drone a little more, or if it doesn’t even matter? I am planning on swapping the stock mufflers and replacing...
  2. SLP FULL or SLP Custom

    Performance Discussion/Modifications (2011 +)
    So I am going to go with SLP love the way it sounds the loudmouth 1. But I wanted to know if some one could help with how this all works. So my question is, should I go with the the full cat back 599 plus install, unless I do myself which I can do with lift and all for free. Or should I try to...
  3. Badlanz Cutouts or LM1?

    Performance Discussion/Modifications
    Well, the quietness of stock exhaust has started to irk me, and I have found two answers that solve this problem. The question is, which one. I have been fortunate enough to get a 2014 R/T AWD almost a month ago, and it has been an absolute dream...other then the exhaust. As a DD, the silence...
  4. SLP LM1 Rattle

    Performance Discussion/Modifications
    Last month I bought a 2014 R/T Max and it was too quiet for my taste so I bought the SLP LM1 as I thought it was one of the better sounding exhausts made for the Charger from what I heard on youtube clips. I bought one and had it installed a couple weeks ago. I love the sound of it except for at...
  5. What sounds like SLP loudmouth but not so...loud?

    Performance Discussion/Modifications
    I want to put some exhaust on my 06 rt, so I've been reading through the forums and finding as many vids as I can on YouTube. It's really hard to tell how it sounds on the videos and especially volume is difficult to tell. I really like the sound of the loudmouth, though. It's got that classic...
  6. SLP LM1 MDS Drone Help

    Performance Discussion/Modifications
    I removed both the resonator's and the suitcase muffler to replace the muffler with LM1 resonators. I do a lot of highway driving and the drone from the MDS is unbearable. I heard the corsa xtreme exhaust gets rid of the MDS drone but I don't have the money to do that right now. Is there...

  8. SLP Line Lock Install

    Just picked up an SLP Line Lock kit from Speedlogix in Florida and installed it. It is pretty simple but I thought I would do a short write up on the install. SLP is really good at putting the kit together. Writing instructions... well, let's just say it's not what they are the best at... :) I...
