Flowmasters Super 40's
 

I finally got me a newer truck. I bought a 2001 F-150 Off Road 4x4. It does have the 5.4L Engine. I have an exhaust appointment monday and I have told the guy I want Super 40's on my truck. I was wondering if the super 40's will sound good? I see on thier site thier for high performance engines but I see a lot of people on here put the standard 40's on. I was wondering If I will hear what like thier sites sound clip is like. So I guese I am asking which will sound better on a 5.4 the standard or the super 40's?
