think you might need to use resonators maybe even just resonator tips the only other thing you can do is use allot of sound deadening material in the back

 

I have just about the same setup on my 05' RT, it sounded great but I got a lot of drone on the highway.

You need to add 2 short straight thru resonators in the rear, it helped my Maggie.

yah there's a lot of drone, i just dont want it to go back to quiet again with resonators on the back

my car had the stock resonators on it when i got it with the current set up, and i had them cut off and tips put on the back, i just dont want it to go back to as quiet as it was before...but yah i was thinking the same thing..may need resonators back on there again...

 

The straight thru resonators I am talking about, look like glass pack mufflers. They are straight thru design, you can look right thru them. It gets rid of the drone and you still have good sound.................

Yeah, I had that same problem when I dualled out my SXT with the Borla setup. Just a whole lot of reverberation but after a LOT of miles put on, it's seemed to settle down. But when we take our long distance trips it kicks up again.
The only fix I could come up with is to switch exhausts with a brand that doesn't have that ailment.
Blastin' Bob's? Zoomers? SLP Loudmouth?

 

i have the same drone at about 2200 rpm but i dont drive on the highway that much so i dont mind at all. I have the same set-up on my 05 r/t and love it. Its all up to what you want.
