Exhaust blowing

[Boxered]

Took my bike for it's 1st mot today, spotted exhaust is blowing from the mid pipe to cans joint, it was fine when 1st fitted but suddenly has given! I cannot get it tight enough to stop. has anyone else had this problem? if so any tips would be most helpfull. Should I use some gaskett silicone on the joint?
thanks in advance

If its a standard system take the spacer out of the cilp - should enable you to pull it up a bit tighter.
Downside is you will prob have to take the cans off to get the clip off.

It's a laser y piece & std cans, already removed the spacer but its still blowing, I'm going to try some silicone gasket compound this afternoon.

the gasket compound i bought in halfords turns out to be non setting type? any ideas as to whether this will do, or should I get some hermetite stuff?

Just a word of warning!!

Laser had a lot of problems because they manufactured the y-piece slightly undersize, but did not then see fit to supply a different clamp. They wanted the user to use the OE clamp. Unfortunately the OE clamp 'bottoms' out before the joint is completely tight. Tight enought to feel secure by hand, but not tight enough to endure the rigours of actual use. It is not the spacer in the clamp so much as the amount of usable thread on the bolt.

The result was usually the cans falling off. They would then drop onto the wheel and the road speed at which this happened would determine how much of the rear of the bike would be destroyed. I never saw one but I am told that it was extremely spectacular. It was certainly very expensive. It even happened to BMW dealers. There is a lot of fuss about this in Germany.

Laser came up with all kinds of 'Heath Robinson' cures such as rods or springs holding the cans in place using various underseat attachment points. Personally I found that a Coca-Cola can shim between the two pipes does the trick perfectly. A mate swears by a Pepsi-Maxx tin!!

Thanks Sandbar, I think the silicone has done the trick, but you've got me worried now!, Pepsi-max eh?, if I can get the silicone goo off I'll try it.

My last set fell off at about 30mph.
I felt a tiny clonk the day before, stopped but couldn't locate the problem.
It would have been the cans coming off the spigots and banging the tail piece.
