Just installed flowmaster outlaws and I love them loud, aggressive, and just down right mean. But the drone at highway speeds is horrible. Do you think dynomat or a dynomat like product would help? I know the trunk area has little to none as far a sound deadening.

Will help alot if done right.

Is it hard to do right? If not where would one have it done at?

its not a hard thing to do at all. I would do the trunk, floor boards and roof to start with.

Just do it your self it's not hard. Definetly the wall behind the rear seats and the trunk floor.

No it does not help. I had a 2010 gt with boomtube axlebacks, which are basically pipe with 2 resonators attached to them. They droned like no other. I did my whole trunk area with dynomat it didn't make 1 bit of difference.

You may want to look into heavy duty undercoating on the underside and a spray in truck bedliner material in the trunk area, that will do the trick!

Ha Adrain that will werk!.. I also thinking Kona stang didn't go far enough or didn't use the right materal in his trunk to kill enough sound. Just doing the trunk is not enough. Just doing the trunk and rear 1/4 panels in my car made a difference in my car. The tunes sounded better and the car became a little quietier. Doing the roof doors and other parts of the interior helped alot also. I just need to get off my butt and do the floor.
I'm not a big fan of the spray on stuff either. I'm not saying its no good but spraying that stuff on/under your car it goes places you don't really want it to go. On your driveshaft, exhaust parts, brake cables...
