Key Features & Benefits – Stainless steel 5-step exhaust pipe reducer 50–70 mm
Stainless steel 5-step exhaust pipe reducer 50–70 mm is a practical option when you want one reducer that covers multiple OD sizes for custom exhaust builds.
The stepped design lets you cut to the required diameter and then weld-on for your final fitment. Listed as 201 stainless steel with a stated ±1 mm OD tolerance.
When is this useful?
Useful for custom exhaust routing or muffler connections where your project may need different pipe sizes between 50 mm and 70 mm OD, and you want to choose the step during fabrication.

Selection & installation tips
- Measure the pipe outside diameter (OD) and select the correct step (50/55/60/65/70 mm).
- Plan the cut line so the joint length and insertion fit your layout.
- Prep surfaces before welding and check for even contact around the circumference.
- Confirm available space for the 145 mm overall length.
- Allow for the listed ±1 mm tolerance and finalize based on real measurements.
Before fitting, self-verify the OD sizes, choose the required step (50–70 mm), and compare your measurements and available space to the specifications listed above.
