    The product and sound are great. Installation was a bear. I could not get the exhaust pipes to come out of the factory muffler. So I ended up using a hammer. Took over an hour to get apart; 10 minutes to put together.

    Flowmaster Outlaw Series is the only way to go. I put the Flowmaster Outlaw direct fit muffler on my 2013 Dodge Ram and it sounds fantastic. I sure am glad that I opted for the Outlaw Series muffler over the American Thunder Series. I haven't noticed any difference in gas mileage but, who cares..... I didn't make this purchase for that purpose.

    Perfect Sound

    My new outlaw flowmaster slip on exhaust muffler has the perfect sound. It is not loud in the cabin and annoying in the outside during acceleration.

    They'll hear you coming!

    This exhaust installed in less than an hour. Presoak the clamp bolts and hangers prior to installation and your old exhaust will come off fairly easy. The sound is great at low rpm's, does have quite a drone at speeds above 75 mph. If you're on the fence about the sound get the American thunder muffler.

    My 2017 Ram 1500 only had 1,000 miles on it so the stock muffler came off with ease and the flowmaster bolted right up as advertised. Took me 35 minutes total and I didn't even have to jack up the truck, just crawled under it. Sounds like it supposed to now. When the MDS kicks in there is a little drone and knock but you have that with the stock muffler too, now it's just a little louder. It's not so bad that I would consider Removing the flowmaster, it just sounds too good.

    Outlaw bolt on

    I was debating for a while between American thunder and the outlaw direct bolt on for my 13 ram 1500. Man am I glad I got the outlaw! Nice deep rumble but not obnoxious. Kept the resonators on minimal drone in the cab. I'll always use outlaw now on any other truck I get.

    Easy install
