If the silencer is not supported, you run the risk of the exhaust studs being snapped in the head  ;)

The Delkevic should come with a tube of exhaust sealer .

It is indeed, but he has not mounted the centerstand rubber stop. He is using the same bracket as I have, but if using the centerstand, it will not hit the rubber stop, had he mounted it. Also, the muffler must be sitting really far back (see my initial picture, where you can see the position of the muffler when it has to align with the passenger peg hole), so the muffler is barely slid on the head.

At least that's the case on my bike. I would have to slide the head half of the exhaust pipes and then mount the muffler half on the head in the other end. But the whole operation would be rather wiggly as a result. And the centerstand rubber stop would not line up with the actual centerstand :(

And to top it all off, the delkevic didn't come with exhaust sealer. I am going to call them next week for sure!

Trigger:
The rubber stop bolts on the back of the bracket and the foot of the center stand rests against it when the center stand is up.
I have fitted a fair few of these exhausts and never had any problems with or with out a center stand fitted. Are you sure that your center stand is not bent or out of shape.

The delkevic pipes come with little stickers numbered 1 to 4 which match the connecting pipe. You fit everything loose to the bike and do not tighten up any nuts or bolts until everything is lined up  ;)

Hey

Here is some pictures to better explain what's happening. On the first picture, I have mounted the muffler via the bracket that came with the exhaust. It shows clearly how the muffler almost can't connect to the head.

On the second picture, same setup, but this shows how the centerstand is not hitting the rubber stop when the muffler is mounted via the bracket.

Lastly, on the third picture, I tried to slide the head more away from the exhaust pipes, so it sat right in the middle of the exhaust pipe and the muffler (still mounted via the bracket). But that gives such a space between the exhaust pipes and the head, that I will never be able to connect the springs and drag them out. It simply requires too much force.

The last picture is without the muffler, so you can see the condition of the centerstand, which to my knowledge is exactly as it should be.

Bryanj:
Take the bracket off, mount the silencer properly and see what needs modifying on the bracket

Trigger:
Turn the center stand stop around  ;)
