    Hey guys I'm back with another couple of questions
    1) Where in heavens name can i get a remap done!? O.o i hear they are awsome but i have no idea who'd be able to do that. and just to make sure, a remap is when the ECU is reprogrammed to give better performance correct?
    2) I was hoping to put on a new exhaust to make my car slightly more powerful...specifically this one http://www.amazon.com/98-06-BMW-Catb...5874631&sr=1-2
    Now should I get a new exhaust manifold with it? Do i have to? Or would i get good HP gains without the manifold?
    And how difficult is it to install a new exhaust/manifold? thanks guys!

    p.s. if anyone can reccoment any other ways to get HP gains let me know!

    Providing that silencer you listed is a straight through design it will give a small power increase. I custom manifold will give more power as well, but I don't think its worth changing the manifold if you are keeping the cats.
    Fitting that silencer should be easy.
    Tuning shops for the remap, not to sure about finding them in USA though, maybe try finding a local BMW forum and asking on there?

    Other easy ways to get power is a CAI, but you've already done that?
