Thanks Myfirstbusa,
Well I just got off the phone with the shop I bought them from, seems the box had a couple holes in it that they knew about and taped up. They didn't think anything was missing
and shipped it anyway.
What was missing was the sealing gaskets and the clamps, the correct clamps. So I have to mail back the extension tubes (mid pipes) and they are mailing me a set of new tubes, sealing gaskets, and the clamps.
It is a bit of downtime when I wanted to ride this week, but that is alright, stuff happens at least they are taking care of it.
Myfirstbusa, I was stuck in between the two as well, the yosh carbon or this. I can tell you that If I had chosen to go the 4 into 1 route, the yosh would have been it. That pipe looks incredible and sounds good too without being crazy loud. I cannot imagine the tsukigi 4 into 1 if it is any louder than the slip ons, lol. The microns I had on it sounded very good and were not real loud. The tsukigi are top notch though and the workmanship really shows. They look like a straight tube that is WIDE open with some kind of canister filter stuck in them like you might use in a fish tank. You can shine a light in them and see all the way to the pistons if you could lol
