So please explain how exactly do you break in a muffler without any deadening material inside of it? No joking around...tell me.
Perhaps you turned down the radio and it got louder? (joke)
You replaced your hearing aid batteries? (joke)
Maybe sound travels differently in your area? (joke)
The annealing and soot thing? I suppose...(no joke!!!)
It's no big deal one way or the other to me...

muff noise
I hear a lot of Fords in town, and i think the ones with the Flows dont sound as good as mine with the Magnaflow. Kind of loud and crude if you ask me. I do have a set of Flowmasters on my 390 Ford, and would like to get rid of them. If you like a lot of noise they are def the best choice. Short/no tailpipe also has a much deeper drone too.

Im buying a 2011 platinum package with a 6.2. Then Im gonna turn the manifolds upside down and run two 4 inch stacks out the holes i cut in the hood. Oh and i will install tractor flaps of course. What do u guys think it will sound like?
