This listing is for one piece.
I do have quite a few more and please just email me and I can check and make sure that I have more on hand.
I can also get you a price for combined shipping depending on how many that you are interested in.
All of them are used and looks like they may have been painted grey at one time. Picture is of a sample for that style.
I also have a variety of styles that I will be listing and they are all for the 6 size.
If you are close by, I do have quite a bit of the original pipe for this size fitting in a variety of lengths.
The 6 designation means that it is for pipe with a 1.315" OD which normally has a 1" ID.
