919 - Yoshimura Dual Exhaust Alignment and Fitting

So I cut/fitted up rubber lining on my exhaust clamps (tighter clamp and reduce vibration) when I found a couple of issues.

1. While tightening the clamp, I was aligning the muffs when it was completely removed with the mid pipe with ease! I was shocked how easy it was removed! I immediately put em back and tighten the screws where the endcan and midpipe meet, however it's not that airtight! I can feel air coming out of it (not enough to blow a tissue paper when placed on top but you can definitely feel there's a small leak)

Is such small leak acceptable? What can I do to improve tightness? Anything to put in the connecting pipes?

2. Related to #1, I pushed the left Yoshi endcan all the way to the midpipe, however it's not aligned with the right pipe which is already fitted end to end with the midpipe. So what I did was not to "push" the left Yoshi pipe to the midpipe so that it will be aligned with the right Yoshi pipe.

Could this be the reason for the small leak that I have? Do I need to check if my midpips are the same?

Anyone out there who have tips on fitting Niner exhausts? Please let me know 😎😎😎

When I did the 900RR conversion, the muffler fit on the pipe was a little loose, so I built up the diameter a little using some aluminum exhaust tape. I think I got it an an auto parts store.
