Emissions Notice

This Top Street Performance (TSP) product is designed for racing and off-road competition use only. It is not legal for use on public roads or emissions-controlled vehicles and does not comply with federal, state, or local emissions regulations. The buyer assumes all responsibility for legal use and installation.

What is a Emissions-Controlled Vehicle?
"An emissions-controlled vehicle is any vehicle equipped with a factory-installed emissions control system designed to reduce air pollution. These systems include catalytic converters, oxygen sensors, EGR (Exhaust Gas Recirculation) valves, and diesel particulate filters (DPF). Most vehicles manufactured after 1975 are considered emissions-controlled and must comply with federal and state emissions laws when used on public roads."
