Just like it says. A friend wants his 360 to be really quiet but make a little more power, he is set on getting duals while he replaces his rusted out EX but wants it really quiet. Also what is a good size, I am thinking 2.25  The engine is a 5.9 magnum with heads shaved .030 very mildly ported heads, we are gonna throw in a roller cam from a 5.2 mag since we have it sitting around and it is a hair bigger. We are also gonna try one of the new hughes air-gap intakes since the motor is EFI and mabey a set of 1.7 MP roller rockers and some GM v6 behive valve springs. I may try to find a cheap set of the bigger 92 93 ex manifolds while we are at it since he wants it super quiet and cheap.

Dynomax Hemi superturbo is a good one for quiet performance. Its a bit longer than the regular superturbo, but I think it only comes in 2 1/2". Ultra flo is not what I would call a quiet muffler. Maybe more quiet than some, but for what you are looking for, it will be too loud. Great performing muffler though...

Check AP Exhaust Products. I had their MSL mufflers from 1990 to 2003 on my 68' Coronet with 318. They are regular passenger stock mufflers .Excellant mufflers and lasted me 13 years. They are quiet and have the correct back in the day Mopar muffler sound. I always loved the way they sounded. They sounded excellant and the performance was really good. If you go on the AP Exhaust website they have downloadable catalogs for different year cars. These mufflers will have what your looking for. When I replaced them in 2003 I should have went with those mufflers but insteadwent with their lifetime muffler and this was done at the same muffler shop. To get a good idea of how they sounded go on Youtube and type in "80 Steps to Jonah". It was a movie with Wayne Newton and Sal Mineo. Sal drove a gold color 69' Charger. In the scene you can hear the exhaust. Look for the scene where he picks up the young looking Wayne Newton. Here is the link. http://www.apexhaust.com/index.php/Catalogs

The above link is 3" exhaust with 14" Dynomax ultraflo muffler. Sounds rather loud to me. check his other videos, he has done alot of research on diffrent mufflers.
3" will be a lot louder than a 2.5, or 2.25 for that matter, system.
John,thats why I turn my hearing aid down when I drive the wagon!!

I opted for corrective surgery instead of hearing aides , should have gotten the hearing aides I guess , but even when I was deaf the DRONE is what drove me crazier .
