Emissions and use

This race header system removes catalytic converters, so Fabspeed sells it for closed-course, track and off-road use only, never for public roads. On OBD2 cars it can turn on a check engine light. Check your state and local emissions rules before you buy.

Not CARB or EPA certified; closed-course use.
