Rebuilds for Bandit hand-fed and whole-tree chippers

Bandit's gas and diesel chippers run hard, and the catalytic converter is a common wear point — it loads up with carbon over the years and starts choking the engine. Instead of paying full OEM, D&S rebuilds your existing converter with a fresh substrate in the original housing, backed by a warranty against manufacturing defects.

We rebuild every Bandit model

Gas or diesel, hand-fed or whole-tree, any year — if it's a Bandit with a catalytic converter, we rebuild it. Models we handle include:

Don't see yours? We still rebuild it — every Bandit converter, any model, same flat price. Order your rebuild → Not sure it's a fit? Send a photo.

Tip: before you replace a cat, rule out fuel and air filters. If power returns with the exhaust cracked loose at the converter, it's the cat. Full symptom guide →
Thinking of deleting it instead? On Tier 4 machines that usually just triggers a derate — and running without the cat can stress the engine. A rebuild is the reliable fix. Rebuild vs. replace →
