My custom exhaust

I thought of sound insulation, but would probably need so much of it I'd be better off buying the OE setup.

Any help would be appreciated.

I Did, like you, order a rather LOUD Axleback muffler and put it on my XD. I was oh-so-thrilled with the idle exhaust sound! Poking it out made a beeeautiful sound too... But highway drone was, like yours, INTOLERABLE. I kept changing back to stock every other week, and decided to try sound deadening the rear area of the car. I did the underbody, rear fenders, trunk floor, and paid most of my attention to the hatch area. I doubled the insulation on the hatch and rear panels near the exhaust and it was sooo nice, I ended up doing the ENTIRE car. The most effective dampening was foaming the empty frame areas and the fender cavities in the back. (Even the bumper) I now have the bad boy on constantly, and have no drone except when the windows are down. The Foam and "Rattle Trap" deadening was not very expensive. Foam was 4 bucks a tall can from Home Depot, and the Rattle Trap was $135 shipped. I used 8 cans of foam. I love driving it now, and my daughter says I made my own Lexus...
