Default Getting rid of interior exhaust noise???

My TA has no muffler so it's straight piped out the back. I have put a layer of dynamat extreme in the rear but it hardly helps. The low drone at 80 mph is very annoying. Has anyone used a reasonably priced material that will help exhaust noise??

try a muffler?

I couldn't help it.

Having no muffler is just going to be drone and loud no real way to aviod it and the dynamat will help but thats all I can think of doing.

I did my whole trunk area with Dynamat also .. And that didnt work so i then stuffed all the back panels with Pink Panther insulation because it was light .
Though both toned it down a little bit, it still didnt get rid of the Highway drone.

Garbage trucks don't sound good dude! Pull that heavy dynamat out and get a muffler. Hooker sounds very good and has almost no interior noise and no drone.

It's only between 75-85 mph in 6th gear when the resonance is annoying. Driving in town it sounds great. It's just when I set the cruise at 80 is when it sucks. I have put a layer behind the rear seats too.
