that should be as quiet as a stock muffler at idle and slightly louder than stock on acceleration, i have the single in/single out version of that one and i love it. :twocents:
country3030's muffler has a nice tone to it, and is fairly quiet.
My 2in/2out magnaflow drones so bad at 1900-2100 rpm it makes the fillings in my molars buzz and my ears feel like I'm coming in for a landing. At higher rpms it seriously pisses off the neighbors, makes ricers cower and scares small children and dogs. Of course mine is connected to a cammed 6.2 with catted Lt's.
