Flowmaster dBX Series Hushpower Mufflers Reviews

Happy Tuner

I purchased this Flowmaster dBX Series Hushpower muffler to replace an inferior product and it has been money well spent! The original sputter has been replaced by a low growl that sounds fantastic!

Flowmaster 50 Series HD Mufflers Reviews

Louder than expected

Reviewed By charlie d (garden grove, CA) Reviewed for a 2014 Dodge Ram —10/24/2015 7:23 AM

I have to say, I'm no mod expert. I had this installed at a local muffler shop for a very reasonable price. The installer said that it was very easy to put in and the total time it took him was less than an hour. When finished, I was really impressed at the sound when starting the vehicle. Perfect rumble. Sound was aggressive but not loud. The issue I had was at cruising speeds. It was alot louder in the cabin than I had read by others.I also have a mopar cai, so that may make the muffler louder
