I have the 14" Dynomax Super Turbo Mufflers with a H-Pipe and 3" to the rear of the car with turn downs and its very quiet compared to the flowmasters its night & day. Now if you have any sheet metal work that was not secured good its going to make noise i fixed mine for the most part.! Quote:
I have the short case on my Dart , it has a nasty drone , I want to try and fit the long case under the car, but against my ultimate goal of being as close to stock as possible for the PS drags, I am going to put an X pipe on the car to see if the drone goes away .

I already have the 14" ones and to be honest they are real nice sounding & for the most part queit and i really enjoy them but i should have gone with the long ones or a good set of Hemi mufflers.! Here is a video of my car now with the 14" Dynomax Super Turbo Mufflers. http://youtu.be/op9hfrhr1pAQuote:
The 14" will be louder than the longer case ones.Run the longest case muffler you can for noise reduction.

Be carefule about the "HEMI" mufflers. I bought a pair from an advertiser here on Moparts. I figured that with 635 HP my HEMI would be louder than the originals which I remember, they sounded GREAT! Well, they must have been reproduction of Imperial mufflers. You couldn't hear the 540c.i. motor in a convertable while cruising, AT ALL! I installed 20" Dynomac Ultaflows and no drone, almost original Chrysler sound!

On the same engine with everything the same, the 20" case Super Turbos measured about 2 dBA at idle and 3 to 5 dBa less at higher engine speeds, all at static conditions. Under load is slightly different but the 20" case version is most definitely quieter and less prone to drone.
Even though they are quieter, they allow as much air to pass through due to the longer internal sections that enable the air to smooth out after the flow reversal (my theory anyway).
