I had the CDC 2 piece speedster cover, and it was nice, but I sold it because I never used it. I thought the 2 piece was advantageous because you can store it in the trunk, but that isn't really as easy as it sounds. Even split in 2, the halves are huge, and once I welded in the rear STB, there was no way they would fit (or if you have any type of sub box, or ANYTHING at all for that matter in the trunk). I would probably buy a 1 piece because it is sleeker, and like I said, without being able to fit it in the trunk, why would you need, or want it to separate anyway.
