I love this. Honestly the closest sound I've heard to my 08 4.6. GREAT VID..now I know the secret to unleashing better sound from my 99 5.4
-
sounds A LOT like my truck actually, except i dont have the hi flow cats

i got a 97 f150 5.4 and already have the si/do flowmaster on it, would you recommend putting the hi-flow cats on?

@Mikebue11 Yes it makes a huge difference. Something went wrong when they did mine though, my cel came on and it wasnt suppose to. Get 4 in tips and the cats and it sounds like a new truck.
