Actually, that's not entierly true...
The V6 doesn't NEED an H-pipe, due to it being 'even fire'. However, it isn't really a bad idea. I'd suggest trying to find a set of GT takeoffs and take that to a local muffler shop. I can't speak for the area you live in, but I got mine put on (including a customed h-pipe) for $100. I doubt it'd cost you much more, if at all.
Ask plenty of questions (especially here), and don't settle for what the first shop you talk to tells you.
