Nissan K21 / K25 Forklift Catalytic Muffler Rebuild
New England Supply House rebuilds the 3-way catalytic muffler for the Nissan K21 / K25 forklift engine — send us your core and we’ll rebuild it with a new catalyst, built to meet EPA/CARB emissions standards, for less than a new OEM unit.
How the rebuild works
Core exchange is required — we rebuild your catalytic muffler, so we need your core. The catalytic muffler bolts off at the exhaust flange — unbolt it and ship us the unit.
- Get a quote. Tell us your forklift’s make, model, engine, and the muffler part number if you have it.
- Unbolt the catalytic muffler at the exhaust flange and ship it to us (with tracking and insurance).
- We rebuild it — we open the assembly, re-core it with a new 3-way catalyst, and reseal it, built to meet EPA/CARB emissions standards.
- We ship it back — usually within 3–5 business days of receiving your core.
Forklifts that run the Nissan K21 / K25
The Nissan K21 (2.0L) and K25 (2.5L) LSI engines are among the most widely used forklift engines — found on Nissan/UniCarriers trucks and licensed across many other nameplates. They run a 3-way catalytic muffler. We rebuild that catalytic muffler via core exchange. Not sure which engine or part number you have? Call 774-701-6374 with your forklift’s model and serial and we’ll confirm.
Pricing: Forklift catalytic-muffler rebuilds are quoted per engine and unit — call 774-701-6374 for your price.
