Does anyone here, who has a F-150 with a 5.4 V8, get Flowmasters? And did you feel a power increase at all? Anything like that? If so what model did you get? Thanks guys.

 

I have a 5.4 and a SI/DO Flowmaster delta-flow 50 with the Flowmaster Y pipe. I can't say for sure that there is more power but it sure sounds like it. I've had guys in 5.0 Mustangs challenge me at stoplights. I just tell them that when you know you've got it, you don't have to prove it to them. And as an added benefit my mileage has gone up about 1.5 MPG. What more could a person ask for?
