DME Racing’s Pro Nitrous Motorcycle Exhaust system is a custom 1 .875″ to 3″ diameter 4 into 1 big tube step header. This system is specifically designed for large engines, NOS motors, and all-out Grudge bikes (short-necked and D-raked). This system fits flush with the bottom case. Some bikes will require modifications to the radiator, see our fitment notes below.
