As above.
Clean the the manifold properly and scrape aroudn the grooves witha stanley blade, you will soon see if theres a gasket in there or not.
Fit new gaskets, the Honda ones are the best.
Get somebody to hold the pipe end to take the weight while you get it lined up nice. I tend to take the heatshield / footrest off to get a good view.
Tighten the bolts down equally till you crush the washers about 1/2, theres no need to make them like pancakes, they just take up the gap and stop leaks.
It wont be flush together but if you tighten it evenly it will be nice and level (parellel) to each other.
Then fit the end-can section.. the stock system bolts to the footpeg so you might have to remove the rear footpeg to get it on this way (locating the end-can section last) but it does make it easier to get a nice seal on the maifold part

Even when you have removed the 'old' gasket have a really good clean out in there as I have found this a couple of times and it is not obvious. Once you have 'all' the old gaskets out you should then be able to see an obvious seat for the new gasket to sit in.
I have always gone for the copper ring type of exhausty gasket (
http://www.ebay.co.uk/itm/COPPER-EXHAUS ... 337894ef83) but am sure the ally ones will work the same, by which I mean they will crush slightly as you tighten up the joint - thus creating the seal required. So if they seem to sit a little proud beforehand, this is ok and should be taken up as they crush/seat properly.

Thanks for the info, considering getting the copper ones as these were used on the front when i removed it. Will give it a good clean out next time i get the chance. Thanks for help

Mate - we have all either learnt the hard way ourselves or been lucky enough to get sage advice from other on here. Wait and see, and in a couple of years you will be feeding this same advice to the next generation - lol
