X pipe is thought to give a more raspy tone than an H pipe.

UPDATE: Manny said they plan on getting a shipment of the old-style Boomtubes in about a week or two. Meanwhile, they are allowing me to keep mine on the car (yay) until then and then they'll ship me the old-style set .

How are you liking yours so far? Mine seem to have gotten a little more broken-in (which is good) but still has a much better tone than the loudmouths.

I haven't made up my mind yet. I'm wanting to see how they sound with the car under load which is not possible here due to the weather. The week or two delay will give me a little more time to make up my mind. It would be great to have both sets here to compare them in person. I still might send this set back. I'm going to try to get a better video up of these so if I do exchange these for the louvered set I can post a comparison video.
