I installed this system on my 2014 Ram 1500 5.7 Hemi. The sound is awesome. Aggressive yet not so loud I can't hear my stereo driving down the road. The system has made a little truck run like a champion. Flowmaster in my opinion is on the top rung of the ladder when it comes to exhaust. Thanks

Highly Recommend

Anybody that wants that throaty rumble this is the set of pipes you need! Completely changed my driving experience in my 2010 Ram 4.7. This was exactly what i was looking for. Bought the 4" Flowmaster Tips separately. The 3" that comes with kit just didn't look right. Have purchased from Auto Anything in the past and will continue to shop here. Super fast shipping!

Sounds amazing!! For ease of install I had a mechanic put it on for me. When I picked my truck up the mechanic said you've woke up your truck! Couldn't be happier. Even though alittle cabin noise but well worth it and the price was the lowest I could find anywhere

I purchased the Flowmaster American Thunder series exhaust kit for my 2012, Ram HEMI 5.7 with MDS. The sounds at first was classic Flowmaster (as I had on my past truck for 7 years), but it the sound and performance "bogs" down when MDS kicks in. I tried to deal with it for a few weeks, by turning the Tow/Haul mode on, but wound up returning to stock set up. If the "bogging down" does not bother you and you are heavy on the throttle all the time -- you will dig the sound. Autoanything had a great price on the kit and the free shipping was excellent!

awesome
