The 3200 rpm drone in my PT drove me crazy for years and yes my spouse hated it because you could not have a "talk" (I think that what she calls them lol) in the car. I dyno matted the whole car and put down 2 layers by the exchaust area and it just did not kill the drone (also had a resonator). Now I was running a Flow Master Delta 90 (it is a load exhaust).

I went to Paul's Custom Exhaust in Snellville and he got it corrected and my cars sounds deeper and better than before and I'm running true duals. This included the cat too so that was about half of the 600. So the exhaust part was like 325 give or take.

So if I were able to pay for a tunable muffler that could actually remove the drone and I could get for 100+ even it was still worth it to me. Oh and sound bites would be cool.
