A big thanks to you all who helped me find the pics of the chimney extension for my smoke n' pit. Took the photo print-out and my chimney's base to the neighborhood muffler shop and Mr. Glenn had me fixed up within 15 minutes! I asked for stainless, but he didn't have any. Ended up with aluminized steel pipe, same as my wife's new GMC exhaust. Thanks again for the help folks, I am excited about my latest mod!
