My rusty ole 3 chbr's are dumped, and with an or x-pipe, man it's pretty loud, i can barely stand it, It has a drone for sure, when i had cat's and stock headers and tailpipes they were extremely quiet.
My buddy has some spintech's street mufflers that are actually pretty quiet in the low rpm's, but sound mean under wot.

My Dynomax's really aren't that loud. It sounds pretty loud in that soundclip, but the video camera was sitting on the ground right between the exhaust tips. At idle it is very, very mellow and quiet. When you nail it, it does get louder, but nothing obnoxious.

I have longtube headers with a 2-1/2" h-pipe. The cam is 224°/234° and .496"/.520". If you have a stock exhaust (manifolds and cats) then the Dynomax's will be much quieter than they are on my fastback.
