Sounds Awesome

Reviewed By Adam W (ABILENE, TX) Reviewed for a 2012 Dodge Ram —11/21/2014 2:46 PM

This muffler sounds great on my truck. I took it to a muffler shop and had it installed on my truck using the factory resonators and tips. It is a little louder than I thought it was going to be, but it sounds mean. I highly recommend all Flowmaster products. This muffler is loud, but not the loudest I have ever had.
