all the information you are looking for is available with a search in the exhaust forum it have been discussed a lot yes its possible no "best" one just do some research and oh by the way you might want to consider using punctuation it is really f-ing annoying to try and read without it

I don't think there will be any brand that will be a direct bolt on. I originally purchased the Active Autowerke catless x-pipe and later added their HFC option. Adding what brand of "race pipes" you have would be helpful unless they're custom.

I wouldn't buy Fabspeed (I have them). The cats are the best quality but the quality of the welds (lack of penetration) and the fitment are sub par.

By far the best xpipe with HFC for fitment and quality is AA

I would have to disagree and say that the Akra system is the best quality and fitment. But this is obviously a completely different price bracket. (And it has an H pipe).

I would also second what M3PO said about not getting the Fabspeed system.

Any muffler shop can do it. HJC have been mentioned as good cats to ask for. Put some 200 cpi cats in the secondary position for more power. You'll need 300cpi in the primary position for no check engine lights... but then, what's the point.
