    The rubber collar/seal between the pipe and silencer has been leaking on my '08 CR125. I put zip-ties around it, but they didn't help much. I put a hose clamp and this was great. However, now the hose clamp eventually caused the rubber collar to split. Oops!

    I recall seeing a billet collar with seals that clamp around this junction area. TM Designs makes a collar but they tend to be bike specific.

    Here is a clamp-style collar that is more what I'm looking for:

    Has anyone used one of these or something else on our Husky pipes?

    I haven't. Matt you could go to a Home Depot or Lowes and look in the plumbing department and get a stainless steel NH coupling. Just use the stainless steel band, cut it down to fit, and install smaller stainless clamps. You are just making a smaller version than they sell for plumbing purposes. I may make one for mine this week as it leaks a little.

    I go to the local auto parts store and buy a section of radiator hose that's the right diameter. Cut off a 2" section and put it on with hose clamps... NOT very tight. They don't have to be hardly tight at all to do the job, and that way they don't cut into the rubber for a very long time. If I need to replace... cut another 2" off the radiator hose. Typically, in the life of a bike, I buy one radiator hose and replace that thingy just a couple times and then the bike's gone, one way or another. And I keep 'em for a very long time.

    That sounds easy and cheap enough Picklito; good tip.

    got to bone yard. cut a hunk of heater hose, go home yank sliencer, clamp it on with spring clamps ya robbed from the heater core area.

    or head to auto parts store and sniff around for scraps of heater hose, buy some spring clamps while yer there.

    Im using Arrow full system and this problem occurs also. I use two ring clamps or whatever you call this ... so far no leaks for over a year.
