has anybody tryed axlebacks on the new F150, I have got 2 sets from a gt 500 brand new and would like to try them. Need info on sound from these muffs.

 

So no one has tryed the axle backs, or eather you dont know what I am talking about. I have a 2004 fx4 and I have two sets of axleback mufflers and was woundering if anybody knows what they would sound like on a f150 or will they fit under the f150.
