MIG welding is arc welding. Any welding that uses electric current is arc welding.

OK So I've managed to get the exhaust off. Apart from the bracket it seems pretty solid.

The bad news is one of the studs has snapped off, fortunately there is about 1cm of the stud sticking out. I'll soak it some more and try to get some mole grips on it or something. Last chance saloon

Well... at least it's only one.
Ya might want to grab some high temp anti-seize for reassembly.

Thanks for the tip Dylan, it'll certainly make future maintenance easier.

Hope all's well with you my friend.

Thanks for all the advice, I'll let you know how many studs I snap


Repeated doses of penetrating oil (Lusol or similar) and at least overnight to soak in before even trying to undo anything like that mate. All that salt and constant rain just conspire against anybody with vehicle.

Apply a bit of local heat too (fire extinguisher at the ready though) because that can work wonders.

If you just went in with spanners blazing youd be asking for trouble imo.

Good luck.

I guess Steve that we will have to bow to the superior technical knowledge, maybe it's just the delivery that needs work.

I have always had good luck re-using seals on exhaust systems on bikes. It is most important to get the head pipe flanges on straight or you will have leaks. You need to hold the flange on straight while spinning each nut on just until it makes contact. Then turn each nut the same number of turns starting with 1/2 turn each. You repeat this for each flange. Do not over tighten the flanges or you will bend the retainers. Take note of the direction the retainers are in when you remove them so that you will know how to re-install them later.
