A dab of grease is useful for keeping the new gaskets in place while you wriggle the new downpipes into position.
What make are the downpipes? A lot of people have had issues with the fit of Delkevik pipes in the past. Tightening up the nuts at the top end first should pull the pipes into the correct position (support the weight at the far end of the collector while you do this). If the bracket at the bottom doesn’t line up neatly with the fixing hole on the footpeg bracket it’ll put a lot of strain on the header which can result in leaks, particularly if the footpeg bolt is tightened up before the header clamps.
That's a valid point, when I got my bike and first changed the gaskets there were two sets in there causing an air leak.
The fact they're a bit of a bugger to get out is probably why the previous owner didn't try harder to remove them.
