Hi, The rear manifold/exhaust gasket is blowing, have purchased a new one, what is the best/easiest way to remove the pipe from the head collar.

Please fill in your signature w/ the year model of what your riding/working on

See - for assistance in filling it out.

The collar should just slide off the pipe after removing it.

The model and year were included in my signature? does this turn itself off?

It is a 93 750, just cleaned all the crud from it and noticed that the rear pipe has a joint on it near the centre stand, looks like I am going to have to cut the exhaust clamp off as the bolt going through it has rusted hopefully be able to replace it with a jubilee clip.

I hve removed the nuts at the cylinder head but the exhaust will not budge needs to be undone at that joint

Sounds like your starting work on that exhaust system from the middle and wondering why nothing budges . You'll prolly have to remove it as a system Front pipe too .

No, not really the pipe I am trying to remove comes from the rear head and and it then joins the main collector box and is fixed via a pinch bolt.

I'm quite familiar with the exhaust and still stand by my previous post . You ain't getting that pipe out without dropping the the collector box . There just isn't enough free space to work it loose . Course you might be the type who whips out the torch and proves me wrong .

Per Clymer

Removal/Installation (1984-on)
1. Place the bike on the centerstand.
2. Remove the muffler as follows:
a. Loosen the rear cylinder exhuast pipe clamp
at the muffler.
b. Loosen the front cylinder exhaust pipe clamp
at the muffler .
c. Remove the rear muffler bolts and footpegs and remove the muffler assembly.
3. Remove the Allen bolts securing the front
exhaust pipe flange at the front cylinder head and remove the exhaust pipe and
gasket. Repeat for the rear cylinder exhaust pipe.
4. Install by reversing these removal steps; note
the following.
5. Install a new gasket into each exhaust port in
the cylinder head. In addition, check the gaskets
between the exhaust pipes and mufflers. Replace
any gasket as required.
6. Install all parts and secure fasteners finger-tight
only. Then tighten the exhaust flange bolts securely
and work back to the mufflers. This will minimize
exhaust leak age at the cylinder heads. Tighten all
bolts securely.
