    Exhaust leak question.

    Hi Gang,

    I have an exhaust leak where the tail pipe connects to the exhaust pipe underneath the bike. (Right about where the foot brake lever is.)

    The packing that is inside the female end is buggered. I can feel exhaust leaking around the connection point.

    Can I wrap the male end with something to fix this? Any suggestions?

    Appreciate any input!

    Thanks All.

    Before trying to wrap something around the outside,
    you say that "The packing that is inside the female end is buggered."

    There is a Gasket that sits inside the Joint - Triumph Part Number T2202115, and costs about £7.00.
    It is available from your Triumph Dealer or On Line from World of Triumph.

    Be careful when taking the Silencer section off, and try not to bend / flex the joint
    as the end sections of the Header Pipe assembly can be broken off.
    Use gentle twisting of the Silencer but keeping it in line while pulling it out of the joint.

    Cheers  :821:

    I'd reinforce what Coconut just stated, the down pipe material is very thin and prone to cracking near the ends of the slots. Fit the best quality graphite seal ring you can get if not the genuine one.

    Thanks guys.

    I ordered an OEM gasket. Hopefully it will be here soon.

    Meanwhile, I am riding around with a bit of a leak down there.

    Is that a big deal?

    Without knowing how bad or exactly where / what angle the gas is coming out at, it's hard to say. I'd be gentle on the throttle until you can get it fixed. It's downstream of the CAT so the gas pressure will be slightly reduced. Might be worth checking with a strip of paper (I don't need to say don't use your fingers, do I?) to make sure hot gas is not blowing onto anything that might get damaged.

    There ARE products that will wrap around the Joint and seal it,
    but this will make it more difficult to remove the Rear Wheel,
    for Tyre changes etc, where the Silencer would normally be removed first.

    Some Members just undo the Rear Mounting and slacken the Band Clamp around the joint,
    then move the pipe out of the way enough to remove the wheel, but this adds to the risk
    of flexing and damaging / weakening those end sections of the Header Pipe,
    so I would not recommend doing this other than as an emergency temporary repair.

    Cheers  :821:

     :028: Absolutely.

    Unfortunately "swinging the can" appears to be common practice in some workshops when doing a rear tyre change. I could probably be heard on the other side of Paisley when I caught a "mechanic" doing it  :233: and I'm sure it was contributary to early failure of of my joint.
