Hello K&S metal has 1/2 inch stainless. When you order it order the next size smaller that will fit inside the 1/2 inch so you can sleeve it to add 45 degree and 90 degree pipe to it. You get the 45 and 90 degree pile from Micro Group there email is
www.microgrouyp.com they are very expensive. The part number for the 90 degree is 90MM-8 and the n45 is 45MF-8 I got 10 of each and it cost $159.78. Now that all you need is some compound and a buffer and they look like chrome. Ed
