Any X or H pipe is great. Some are better quality but they all perform the same function. Just pick your price range. As far as mufflers go there are lots of sites that have the muffler sound clips so you can listen and take your pick. There is a stang in my area I would love to run down and find out what set up he is running. It sound incredible! As far as the aluminum muffs rusting, no they wont rust but aluminized metal is not as strong as the SS and I don't believe it can be welded like the SS can. Pay extra and get the SS, you get what you pay for!
