They work fine with stock hook ups. The difference is one looks like an "H", the other looks like an "X". H pipes sound more old school i guess you could say as the X pipe sounds more raspy and not as deep as an H. X-pipe's i beleive give you more performance gains, but i could be wrong on that. Alot of 5.0's mainly stick with an H-pipe while the modular 4.6's go with an X..

someone once told me that the H gives you more low end, X gives you more top end, and the Prochamber gives you both. Dont know if its true, i run a X on my windsor
