Driven Racing (DSBlock 2) Black Exhaust Smog Block-Off Plate

Driven Smog Block Off Plates are designed to eliminate the back fires from your bikes exhaust caused when unburned fuel and air meet the hot chamber temperatures in a bikes exhaust. The plates cap off the injection of air into the exhaust cycle to help reduce or eliminate the back fire situation through capping off of the air lines from the PAIR valve. This is most commonly encountered after the use of a Power Commander or like product is installed on a motorcycle and the fuel maps have been changed for increased performance. These plates will help the motorcycle to run smoother as well as enable a more precise mapping of the motorcycles fuel system. These plates are made from 6061 aluminum and anodized black for durability and corrosion resistance. The package will include the plates, a rubber air box cap, and basic instructions to bypass the pair valve air lines. These are intended for off road, closed course, competition motorcycles only. Please consult your local laws before use on a motorcycle for public streets.
