'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.
Mine are date coded repro mufflers I bought in 2005 from Josh thru Dale's Cuda Shop. They are very free flowing and do not have a drone to them. I would buy another set in a heartbeat if I needed them!

Wrong.....The Dynomax Super Turbos are some of the least restrictive mufflers, at least in the 2.5 or 3" varieties. Add a resonator farther back to cut the drone.
R.
 the mufflers you want to switch to are straight thru design , it's only going to get louder.
What about a straight through muffler with a resonator farther back?
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 ?
this is the route I was thinking of doing - but I think the resonator is in the front on the hemi e bodies - , round muffler in back - I asked this before - my setup I was contemplating is HP manifolds, 2.5 pipes to ultraflows, over axle to 2.5 round mufflers in stock location to tips - or would this be "too muffled" or restricted - if through a second strait through muffler?

Joe you are right , they call the front muffler a resonator , I look at resonators as round canisters , not oval muffler looking items . is the front resenator on the ebody center in , center out or offset ?
anyway I needed to quiet down my Diesel truck and added a round canister straight thru muffler ahead of the muffler .
My 69 Dart drones , it has the short hemi turbos on it , I'm going to change them out for the longer ones and add an X pipe , might try the X pipe first and go from there.

resonator should be offset inlet center outlet I think - any thoughts on what I described as a setup with 4 mufflers? - Didn't the Silver Bullet use 4 Caddy mufflers? - Not that I'm anywhere NEAR that territory lol!
Your setups looks good , it's what I would do if I had the room in the rear of the dart for resonators .
The Sliver Bullet had dual duals , they Y'd off the header collector to 2 seperate pipes , I don't recall reading what they used for mufflers .

I had a K5 1970 Challenger 440-6 survivor and it had resonators which were about 18" long and were placed just about where the back seat would be, I took them out because I wanted more noise. The car belongs to a mbr here who lives near Detroit

Please let us know what you do and how it turns out. I have the same setup and the drone (at 65mph) is driving me crazy. I am also skeptical of the Dynomax but it sure sounds like the best of both worlds if they really work. My stock install did not have a resonator. I am thinking they thought it was a waste of time on a 318.
