    Super 44 rumble

    Bought this for my son's 96 c1500 5.7l with stock exhaust up to mufflers. I had a 70 series big block flowmaster on there before. He wanted it to be louder and it definitely is louder. It has more interior resonance than the 70 series. It is louder outside the truck too, but not as much of the old school flowmaster 40 series sound as I would like.

    Super 44 meow delete 5.8 351w

    Got it put on my 93 f-150. The truck has a 5.8 351 Windsor with stock manifolds running 2 1/2 inch from each down pipe into each inlet and running it out the back with some 3 1/4 inch rolled tips. It gives the truck a good rumble but not super obnoxious. You can still listen to the radio at a comfortable volume and will drone up hills with the cruise on but is pretty quiet cruising.
