They are loud enough to hear the engine and have a sweet growl at low speeds.
They do not drone at any speed and are totally quiet at highway crusing speed.
If you are looking for the thousand horsepower louder than it should be , go with flowmasters..



I have 3" tti exhaust, H-pipe and Dynomax Super Turbos with a hemi. I like it a lot. It's louder than stock but not as loud as Flowmasters. I find loud mufflers and highway drone obnoxious as I get older.
