On chipper engines the cat loads up with carbon and chokes exhaust flow. Common tells:
Bogs under load, slow to recover.
Can't hold rated speed.
Tier 4 derate or fault light.
Restricted exhaust, extra heat.

Deleting usually causes more headaches than it solves — running without the converter can throw the engine out of spec, and on newer Tier 4 machines it often won't work anyway (the engine monitors the cat, so it can flag a fault or drop into a reduced-power derate). There can be warranty and compliance downsides too. A rebuild gets your power back the right way for a fraction of OEM.
