I think it sounds better in the video than it actually sounds.

I had my X-pipe custom fabbed, as for the 550 at 2.75" piping, there is not one readily available.

If you do end up going the x-pipe only route, make sure to zip tie open you exhaust flaps.

I have the m5 muffers, custom x-pipe(replacing oem center muffler) and the flaps tied open. I'll upload some videos with both the flaps open and closed. Pretty distinct difference, for the better, in terms of volume and a tad bit of tone change.
