Key Features & Benefits – Stainless steel exhaust pipe reducer 2.5" to 3" (63–76 mm)
Stainless steel exhaust pipe reducer – 2.5" to 3" (63–76 mm) – 139 mm length is intended for OD-to-OD transitions when joining different pipe sizes in exhaust/turbo/intercooler/intake-style piping.
Made from stainless steel with a mirror-polished surface, designed to step from 63 mm to 76 mm OD where a clean transition piece is needed.
When is this useful?
Useful when your setup mixes 2.5" and 3" OD sections and you want a straightforward transition part for a clamped or welded joint.

Selection & installation tips
- Measure your piping outside diameter (OD) to confirm you need 63 mm to 76 mm.
- Many components are specified by inside diameter (ID); match OD-to-ID correctly for your joint style.
- Test-fit dry and confirm insertion depth and clearance for the 139 mm length.
- For clamped joints, use correctly sized clamps; for welding, prep edges for full, even contact around the circumference.
- Account for the listed ±1 mm tolerance and base final fitment on real measurements.
Before fitting, self-verify OD sizes (2.5" to 3" / 63–76 mm), joint style (OD/ID), and available space for the 139 mm length, then compare them to the specifications listed above.
