Servicing exhaust pipes has never been easier. Working with exhaust pipes requires a special tool to move and smooth metal pipes evenly easily. The Powerbuilt Small Tailpipe Expander 1-1/8 Inch to 1-3/4 Inch is a specialty tool that expands exhaust pipes, rounding pipe ends, and removes exhaust clamp grooves. The small alloy steel expander works on 1-1/8 inch to 1-3/4 inch internal diameter exhaust pipes. Set the needed diameter with the lock nut and snap ring, insert the expander, and turn the heavy-duty hex bar with your ratchet. The Tailpipe Expander Set meets or exceeds ANSI standards and comes with a lifetime warranty.
