Default Downpipe fitting Tips...Any

Going to have a go at changing the rusty downpipes for the nice new delkevic set i bought recently. Its my first time doing this so was looking for any advice/tips that might make it easier on my knuckles...
Will i need to move the radiator/pipes etc...to do the job. If so i suppose i'll swap the coolant while im there.
Any advice welcome.

to be honest i didnt take anything off the bike besides the fairings to get the pipes on/off. i would highly recommend some swivel bits for your ratchet set to make it easier on yourself.

Make sure you use new gaskets between the pipes and the head. They look like copper crush washers.

Well had a couple of hours this morning so made a start, pics below. No real trouble apart from having to undo a million bolts hope i remember where they all go. Also moved the rad out of the way as i was damaging the fins undoing the centre exhaust bolts so i dropped the coolant too. The 2 centre inner exhaust studs came out with the nuts stuck to them so i might have to order some new ones. Haven't put the new downpipes on yet as the new exhaust nuts haven't turned up yet but should be here tomorrow.
Pleased with how it all went and still have all my knuckles intact.

Now that we are looking at it. When you use this stock "front end" of the system to feed a single can, don't they just stick a plug in the left side outlet and feed everything to the right side?

Congrats Roar,
you got em of without any broken studs. Allow yourself a big sigh of relief. I broke 2 the first time my exhaust came off. Took me nearly nine hours to drill the buggers out and re-tap the threads. There's no joy in that until you've finished.
Three tips:
1. Get new gaskets
2. Clean very thoroughly where they seat preferably with a Dremmel and brass brush attachment.
3. When you've got the exhaust back on use a torque wrench to finally tighten the nuts. You'd be surprised how little they need tightening to do their job. Go too heavy on the wrench and you'll ruin the gaskets immediately.

Hmmm.... I've just thought of another tip.... four tips then.....

Get some high temp anti seize spray. apply liberally to the nut threads. Next time you do the job you'll thank yourself. Check the nut torque next time you give a service just to be sure nothing has worked loose.

Hope that helps. Good luck.
