Need muffler suggestions

Hello. I have an '02 F150 Supercrew FX4. Bought the truck used and prior owner had true dual 2.5" o.d. pipes installed with separate 28" glasspacks. I don't care for the sound or noise level. Anyone recommend a good dual in/out muffler that's freer flowing without as much noise? Might be hard to find a dual in/out with the same spacing betw the pipes (5 1/2" center to center). One that looks appealing is the Flowmaster 70 Series Big Block II. However it has 2 1/4" ins and outs. Thanks for any replies.

You can use regular mufflers just turn them on their sides. Dynomax Super Turbo's are quiet but flow OK. Race Magnums or Magnaflows are OK too.

yup get 2 ovals and they will fit, our truck has 5.5" center to center spacing and it had superturbos till i got ahod of it, now it has 2.5" by 28" glasspacks. Sounds like a truck should except now it sounds like a v6 at idle after a long haul with a load. Magnaflows should be a pretty good bet for ya.
