Cracked or warped original manifold housings
Broken flange sealing at the downpipe connection
Noise from a leaking right-side exhaust manifold
Failed emissions-related exhaust sealing on listed vehicles

Installation Notes

Verify year, make, model, engine, emissions equipment, and right-side position before ordering.
Fitment varies by California emissions, air pump, catalytic converter, and heavy-duty configuration.
Use the included gaskets and downpipe hardware during installation.
Inspect the cylinder head, studs, and mating surfaces before assembly.
Confirm single-exhaust or listed emissions configuration for Dodge B250, D150, and Ramcharger applications.
