    4" FloPro Exhaust with and without muffler sound difference video -2016 Ram 2500 6.7L

    I'm posting this video I made of the difference between my 4" FloPro Exhaust system with and without the muffler because I had a hard time finding sound bytes myself when looking for an exhaust system for my 2016 Ram 2500 Cummins. It's not the best sound quality, plus it's vertical video with my iphone 7. Hope it helps someone, I added the muffler a few days ago because I got tired of the highway drone towing and the city raspy exhaust noise.

    I have one of my 5" straight back. I was surprised it doesn't really drone all too bad except around 2300-2600RPM. Cold start with Exhaust brake on is a good way to tick off the neighbors though. Hahaha

    Yeah that's another reason why I threw on the muffler because when I remote start this beast in the winter she's a screamer in the cold weather with a straight pipe, never had any neighbor complaints mostly because I think they are too scared to say anything or they just enjoy the idle of a straight pipped Cummins

    ...have you compared the cab noise between both? Also, what did you end up staying with, w/ or w/o muffler?

    4" pro flo stainless w/o muffler is the exhaust im getting. I love how it sounds! I want a nice tip on mine though. Most likely a 5" tip 4"exhaust.

    thinking this one!

    I got some horrible cab drone towing trailers uphill on the highway, even without the trailers it was deafening my right ear to the point of almost wanting to pull over. I haven't had the chance to test highway up hills at a constant rpm to know the difference yet but I'm sure my right ear will thank me for the muffler. As of right now the muffler is installed, its only been on since last Friday so still to early to tell, I will let you know. Drove to Boston from Middletown NY and averaged 24.3mpg on highway 70-75mph this past Saturday with the muffler, only hit 21mpg from Middletown to Lake George last year with just the straight pipe.

    Now that you've had the muffler on for a little more time how are you liking it compared to the straight pipe?
