I bought this expander because I had some cast copper bends that didn't fit some EMT tubing with the same outside diameter. I was working on a patio gazebo and needed elbows to make the transition from vertical to horizontal. I heated my elbows with a flashlight, heated the metal, and then used this tool to enlarge the end holes. A total of eight ends were made and the tool worked perfectly. In my experience you will have no trouble changing the shape of the muffler pipe. Before using the expander, I took it apart and applied high temperature bearing grease to the fine threads and friction points. I look forward to passing this tool on to my sons long after I'm done with it. This is a quality item that is built to last if you use it for its intended purpose. I bought this tool mainly based on previous experiences with other Lisle car tools, which I still have after many years. You get what you pay for, that's why I buy the best. (Made in the USA)
