Note: This tool is universal and not vehicle-specific. It services exhaust tubing within the stated diameter range. (That universality is how the OEM positions it.)Make clean, leak-free exhaust connections without a hydraulic expander. The Oni Tools Pipe Stretcher Kit uses an impact wrench to expand exhaust tubing from 1-5/8" to 4-1/4", even in stainless steel. Precision collet adapters deliver smooth, round stretch for slip-fit joints, muffler installs, Y-pipes, and reducer work—on the vehicle to save rack time. The impact-driven cone provides fast, controlled expansion and consistent wall support to reduce splits. Organized in a heavy-duty molded case, this set covers popular sizes and serves as an alternative to Lisle 17350 with compatibility across 17350, 17510, 17520, 17530, 17540, 17550 references. Built for professional exhaust shops yet simple enough for weekend builders, it’s a dependable way to fix alignment issues, seal leaks, and finish custom systems with confidence.
