I ended up getting a FM70 put on yesterday to replace my 40. Very happy about it! Perfect tone, quiet when I want, rumbling and roaring when I wanna hear it!
Glad to hear you decided with that one. We have a Flowmaster on our 1986 F150 302 4x4 and so far it has been pretty good. But it is quite all the time never gets loud. If you want a loud truck we just fire up our 1984 B2 4x4 with no cat pipes and has a thrush pack with pipes on the stock pipes. Not to mention I am liking the Banks power pack on our 02 V10. Man all I am missing is magna flow on one of the trucks LOL. Anyways that is a nice muffler as far as I have seen.

Nice. I am trying to talk the wife into letting me swap out the stock muffler with a FM70. I am making head way on it.
Out of couriosity, what did something like that run ya. If you don't mind me asking.
I bought the Flowmaster from a local race shop. Someone returned it with no box so i got it for $40 even Then i cut out the old muffler with my sawzall and clamped it up and took it to my buddies exhaust shop and paid $10 to weld it up
When the Flowmaster rusts out in a couple years(NW Indiana salty roads) I'll probably go with another FM70 but go back to a single 3.5" exhaust.
