Non-EPA catted downpipes utilize ultra-high quality and high performance catalytic converters, that balance exhaust flow with effective emissions conversion, and are also for off road use only. The EPA Catted Downpipes are legal for all states that don’t have CARB regulations. None of our downpipes are available for sale, shipment to or use in California.
