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.

I really liked the way the banks monster exhaust sounded. Just didn't wanna drop the $$$ on it when I had a perfect exhaust just the wrong muffler

 

Ya I know what you mean. I like our exhaust on our 02 alot.

Did you just swap out the stock muffler?

 

Any chance you could post a sound clip, I think I am going with the FM70 also

 

The PO put a custom catback system on with a flowmaster 40 si/do exiting behind the rear tires

 

I will do one in the morning and post it. It'll be a cold start and maybe I can try and get one running through the gears in cab or something

 

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.

 

Yep me too, I have the ok to do it now I am just deciding on the FM70 or the 40. I cant find anything around here that has either 1 to listen to.

 

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.

Here's a video of in cab. Just cruising through town.

 

Don't remember price but Summit Racing had the cheapest fm70 when I did mine.

 

Well come to find out I have a FM44 delta flow. Stopped at the race shop today and someone had mislabeled the part -_-

I guess it's not that bad because i am enjoying the sound now
