'70 Challenger, 440. TTI 2.5" system with X-pipe. Currently have Dynomax Super Turbos on the car. My understanding is they are more restrictive than a straight through muffler like the Ultraflo or Magnaflow. In addition, I have the typical drone in the 1500-2000 rpm range.
Would like a quieter sound so I can hear the radio, have a conversation, and not have to wear earplugs. However, want the badass sound when I stomp on it.
So, what are my options to have a straight through system, no drone, able to have a conversation while cruising, and nice sound when I stomp on it. Don't want the Dynomax VT's because I don't trust moving parts in a muffler. Thanks.

 the mufflers you want to switch to are straight thru design , it's only going to get louder.

dynomax VT sounds like exactly what you want....straight through, aggressive when on the throttle, drone free at cruise....
or how about just putting some quiet, restrictive mufflers on, then electric cutouts in front of them hooked up to a normally closed vacuum switch? vacuum applied (cruise) and you have no power going to them, and exhaust flows through the mufflers, stomp on it, vaccuum drops to 0, you get electrical current which opens the cutouts?

Ihave the Dynomax turbos on my stroker without any drone issues. I believe that my B body has more pipe after the muffler than an E body though.

I have been running the super turbos for 13 years on my SB and BB since 2005 with no drone. I run headers and was wondering if the drone was more likely with stock exhaust manifolds??

I know, but I worry about that little flap making noise, getting stuck or the spring breaking.

Do your pipes go all the way to the back of the car ? Mine do and I run a 3" X-pipe system with the Ultra-Flows and its not to bad. I listen to the radio and talk to anyone in the pass seat. Yes it is a little noisey but not bad to me for what it is. But if your tail pipes are not to the rear of the car it can be anoying if the pipes come out on the side of the car. Ron

Yes, they go all the way to the back and have the stock type tips.

I the box tips make more noise I went to downturn tailpipes and its definitly quieter Plus the stock ones are barely 1.58 inch where they enter the tailpipe
Mine are the TTI stock appearing tips and are the same size as the rest of the system. They'll be staying on.

Hemi E bodies had a resonator at the rear of the tailpipe so you could surely go that route with a straight thru canister type muffler or a factory resonator ?

An insulated trunk divider helps...
along with a sound deadening matt on the floorpan underneathe the rear seat. Believe it or not, certain mufflers will vibrate the floorpan to cause a droaning sound at certain speeds. I did a full floorpan on a '69 runner with Flow(rust)master 40 series 2 chamber and it quieted interior noise alot! As for muffler choice with good flow and sound, I'm stuck on Borlas.
