I am upgrading my exhaust to some Bassani pipes later in the week. I picked up some V&H gaskets, but I would like to know if I can reuse the stock flanges. They only have about 1,800 miles on them.
I don't know much about 'chinery but I think if the flanges are not somehow damaged they are good to go. I am on my third set of pipes using the same flanges because I do not think they are an part that wears out.
Most people use the old flanges.
When you tighten the nuts at the flange do not over tighten them, just get them a little more than snug. Check the nuts a few times shortly after you start riding with the new exhaust.
