Competition use only. This system is sold for sanctioned racing and closed-course use — not legal for sale or use on pollution-controlled vehicles on public roads. Removing or defeating emissions equipment (DPF, EGR, SCR) on a street-driven truck violates federal law. Read the Off-Road Use Policy before you buy.
