Hi Guys,
I have installed 2 1/4" aluminized pipe back to two stainless Magnaflow mufflers then over the axle to Cuda tips.
We installed a "H" pipe behind the Gearvendors overdrive at about 14" in front of the mufflers.
It sounds good at idle with a deep throaty sound. Problem is everything sounds good until I hit 2000 rpm's, then the drone is so back you can't hear yourself think.
I called Magnaflow and was told to put a 4.5" round x 20" resonator in front of the "H' pipe, which will put it under the seats.
I want a nice low rumble sound but I want it to be as quite in the cab as possible.
Does this sound normal or should I change mufflers? Any advice will be appreciated.
Cheers!
Mickm
Put a pair of these behind the axle....

:iagree:, I would try that first , if you decide to change mufflers I would Dynomax super turbos or Hooker Aero chambers
1 Wild R/T and Chryco Psycho, thanks for the advice. I'll get a pair coming today and let you know how they work.
Cheers!

One question guys before I order, will putting them behind the axle get rid of the drone noise in the cab? Magnaflow told me to put them in front of the H-pipe.
Just wanted to ask.
Cheer!

Chrysler put resonators at the rear on Hemi's worked fine.... I've done resonators at the rear on a few cars, always worked... The drone comes out the back not through the pipe...
I have the same issue with Miss NIKKI.... Love the rumble at the stop light... but at 70MPH the drone is a killer. I keep earplugs hangin' on the mirror!!
@blown motor (https://forum.e-bodies.org/mlist/blown-motor_52) can verify! :cooldance:
:rofl: :haha: :rofl: :haha:
x2 on the Aero Chamber mufflers. They produce a mellow rumble and no drone sound. Extremely well made but a little on the heavy side. Installed the 2-1/2" Aero Chamber mufflers on a 36 roadster with 302/headers/ AOD/9" four-link rearend/ out the back with 3" SS tips.
I have the Magnaflow 2-1/2" system and added their 6"x6" race muffler either side of the gas tank, absolutely zero drone, sounds great, has a good rumble, barks a little on WOT but isn't at all obnoxious, love it
Thanks for the input guys, it's greatly appreciated. I'm about to order them now.
blown motor.....My drone is in a 340 ;)
Cheers!

Put a Hemi in then :cooldance:
Chryco Psycho, While I think that is a great idea, I am older and all about cruzing in comfort and getting affordable gas mileage. So the Hemi doesn't fit in my plans.
But for the record, I do love the hemi!!!
Cheers!

Hell. ol' BIGS is 63.... put a HEMI in it :banana: :banana: :haha: :haha: :haha: :haha:
If you hve to live with the drone it might as well be a Hemi drone :haha:
UPDATE!!!!
I ordered the resonators 1 Wild R/T recommended and had them installed this morning.
The sound coming out of the rear of the car is now deeper and more mellow and sounds really good! I drove it 20 miles back home on the interstate at 75 and the drone appears to be gone. There is a, what I will refer to as a "Muscle car" exhaust sound all the time, which is a bit louder than it was before but again, it sounds good!
I am very pleased with the results and want to thank all those who chipped in with advice and ideas, especially 1 Wild R/T for the winning entry.
This is a prime example of what makes this a great site................great people willing to help another Mopar enthusiast.
Thank you one and all :banana:
Cheers!

Lucky Guess... :cheers:

Good to hear ( pardon the pun! LOL ) I've had those vibrant resonators for a few years now to put on. Still haven't got around to it though. Good to know they do the job! :bradsthumb:
Hmmmmm another update...... :wrenching:

Nice, and no resonators to drag.
