I wish you luck mate and sorry I can't help you.
I had a lot of trouble with my 1500 exhausts over the years, replacing, first the o/s then the n/s, then the o/s again. All three were second hand and looked in good condition when I bought them. The trouble being that they rust from the inside-out, plus the fact that the drain hole is in the wrong place (up front), when it should be at the lowest point (at the rear).
I certainly don't recommend buying them on Ebay, or by looking at pics of them, because the chrome will look OK on the outside, whereas the steel behind will be paper thin.
On top of that, you'll find that the flanges on the centre collector box will be wafer thin and break off when you try to remove the exhausts. If you think you can repair those flanges (welding), then be prepared to repair the other flanges from the down pipes. To make matters worse, removing the down pipes will guarantee you shearing, at least 2 manifold studs.
If you decide to replace the whole system (as I did), then make sure you have a few spare studs and a 6 copper gaskets, as these don't come with most systems.
Last year, I replaced mine with a complete Motad system (collector box, not X/over pipes) and it's now quieter than the OEM system.....all for less than £650
Think I'm going to go with the stainless ones, a bit more than I wanted to spend because I'm tight but the best course in the long run.
Typical though, just when I was thinking of selling and upgrading to an a 18, will have to put it on hold for a bit longer.
I doubt you will regret changing out for the Motad Stainless ones George, I loved mine when I changed out the pipes on the 1500. I went the full hog and did from manifold to the back in one hit, because I figured that the down pipes would need doing not long after having to do the rear sections.
Spendy, but worth the money in the long run.

Slipped them on last night and it has transfomed the bike, so a happy little fat chap again now.
