you can very easily do this. but remember to keep the pipes even or in the winter when its cold, one will "smoke" a lot and the other will do just about nothing. A Y connecter to split would probly work better. Just talk to the garage that is building the exhaust for you and they can do some pretty whicked stuff you talk to them right. If you wanted (demending on the money you have and the time they want to put into it) set it up so the pipes shoot out the sides, or though your rear bumper... could look pretty good depending on your style. A muffler (exhaust) shop should have a pipe bender and then they just weld the pipes you want onto the end of the custom bent pipes. No big deal. And it shouldn't cost much either. if you don't go though any body parts
Good luck!
