The two front pipes use a spring fit system to reduce the possibility of damage. (Springs are mounted between the pipes and the engine)  

Accepts the original Lambda sensor (O2 sensor) using your bikes existing engine management system, no modifications required.

Passengers frequently complain of heat from the original catalytic converter, the large internal surface area acts as a heat sink and radiates the heat to the passengers leg or luggage, our exhaust allows the heat to pass cleanly through to the muffler. This enables us to lose the covers and show a much cleaner rear section.

This does not accept the original heat shields.

Fully compatible with the OEM and Black Widow mufflers / silencers, will also fit with any other muffler you are currently using on your CRF 1000 original header. Please note your bike will become louder without the catalytic converter.

2 Year Black Widow Unlimited Mileage Warranty.
