I would get the GTHaus or Eisenmann if it wasn't so pricey, both make top notch exhaust systems. The way I see it, X-pipe + aftermarket mufflers/muffler delete and quad tips will give you a similar look, and somewhat similar sound quality for $400-$500 so it was a no brainer for me cause I'm personally not willing to dish out over $2k just for an exhaust. But at the same time having a high quality, name brand exhaust will certainly earn you some points from those who know what they are looking at. Like if I was at a show and had to vote for 2 w204s with the same exact mods, with the only difference being one having the xpipe, muffler, ebay tips, and the other with a GTHaus or Eisenmann exhaust, I'd give my vote to the w204 with the GTHaus or Eisenmann lol. Lastly, I don't really know what you mean by "Double X-pipe"
