Thinking about deleting or gutting your cat instead?

A straight-pipe looks cheap — until it costs you a machine, a fine, or a contract. Three reasons it’s the wrong move:

⚖️ It’s a federal crime — and you pay

Removing or gutting a catalytic converter is tampering under the Clean Air Act. The EPA fines ~$5,500+ per violation, and the operator is liable — not the shop. A deleted machine also fails the emissions checks most municipal, utility, and government tree contracts require.

⚙️ It can wreck the machine

Modern chipper engines are tuned to run with the converter. Pull it and the ECU throws codes, drops into limp mode, and derates your power — you trade a running machine for one that fights you all day.

🔒 It’s permanent — no undo

Gut the converter and the original core is destroyed for good. When you need it back (inspection, resale, a contract), your only option is a new OEM unit at $4,500–$9,000. A $1,150 rebuild keeps the original working and legal.

The rebuild is the smart move — legal, contract-ready, machine-safe, and a fraction of OEM. Call 774-701-6374.

Frequently asked questions

Which wood chippers do you rebuild catalytic converters for?
We rebuild catalytic converters for all wood chipper makes and models, gas and diesel. Our most-requested are Bandit Intimidator (18XP, 19XP, 19XPC, 21XP), Morbark Eeger Beever (1821, 1922, 2131, M18R, BVR16, BVR19), and Vermeer (BC1000XL, BC1800XL, BC2100XL), covering Cat, Cummins, Deutz, John Deere, Ford, and PSI engines — but we’re not limited to these. If your machine isn’t listed, call 774-701-6374 and we’ll confirm fit.
How does the core exchange work?
Order your rebuild online or by phone, then ship us your existing converter (the core) with tracking and insurance. Full shipping instructions arrive with your order confirmation. Once your core arrives we rebuild it and ship it back.
How long does a rebuild take?
Approximately 3 to 5 business days from the day your core arrives at our facility, plus shipping time each way. You receive tracking as soon as your rebuilt converter ships.
Do you offer pricing for fleets and repair shops?
Yes. Tree services running multiple chippers and repair shops servicing customer machines can call 774-701-6374 or email jason@newenglandsupplyhouse.com for multi-unit pricing and priority turnaround.
Is the rebuild warrantied?
Yes. Our rebuilds are warrantied against manufacturing defects in our workmanship and materials. Because a wood chipper’s operating conditions — excess heat, fuel or oil contamination, or physical damage — can affect any converter, the warranty covers how we build the unit, not damage caused by the machine. Questions? Call 774-701-6374.
Do your rebuilds meet EPA emissions standards?
Our converters are built to meet the EPA emissions standards for your engine. We are not an EPA-certified facility, but the catalyst substrate and build are specified to meet the original emissions requirements for your machine.
