Mufflers Overview
The muffler (and resonator) reduces exhaust noise; a rusted-through or blown muffler gets loud and can fail noise regulations. Van Horn Truck Parts carries mufflers and resonators cross-referenced to Nelson, Donaldson, and Automann part numbers.
Match by inlet and outlet diameters and orientation, body diameter and length, and mounting.
Mechanic & Fitment Specs:
- Match by: Inlet/outlet diameter & orientation, body size, mounting
- Cross-references: Nelson, Donaldson, Automann
- Buying tip: Match inlet/outlet orientation, not just diameters
