Too quiet with just the muffler . Had to cut out the resonator. Sounds pretty throaty now probably perfect for a lot of people .

I went online and watched a lot of videos of all kinds of different mufflers in the Flowmaster super 44 muffler give me the sun that I wanted it has very deep Bello when you take off but yet when you get to speed it mellows out this is the second Flowmaster muffler that I have phoned and I will be buying another one whenever this one goes bad already get a new vehicle
