    I hesitated buying these because I thought they would be to loud, but I'm glad I got them. Not only is the sound just awesome, but it's not obnixious loud like I originally thought. Don't get me wrong they are loud but it's not to much. Chances are if your looking for an exhaust you trying to increase the sound and this is the one you need. Very raspy deep tone and I can tell you first hand it will turn heads. This exhaust will transform the attitude of your ride. Installation was a breeze, however it does take a little bit of time to get them just right.

    Just installed the loudmouth today. Had to wait eight days for shipping because I live in canada but it arrived hastle free. Install took around two hours for me, could be done in less for the experienced wrench man. It was easy and when I fired it up ohhhh man it sounds sweet. Just a note if your picky like me you should start with the drivers side first as it helps with alligning the fitting for the other side so they both stick out the exact length. Such a great product and really makes you feel like your driving a muscle car. Now I need more thanks AM

    Just finished installing my Loudmouths. Installation took a little longer than anticipated because a couple of the exhaust hanger bolts were apparently crossthreaded from the factory. When I went to back the bolts out they were binding and I knew they were crossthreaded. Upon reinstallation of the bolts, they would spin out and could not be torqued down tightly. If this happens to you, a little Loctite Thread Locker will fix the problem. You may also need to grind a quarter to half inch off of the driver side exhaust tip hanger rod. The rod is a little long and will touch the rear bumber frame thus preventing the proper extension of the tip through the rear plastic fender exhaust cutout. Delivery was lightning quick - ordered them on a Sunday and received them Tuesday afternoon!The Loudmouths sound great !
