Almost every Par system works off the same principal, pulling additional air from the airbox to feed to the exhaust ports and provide more air to the hot gases so they burn up more and better. There is no need to remove the system and lose all the parts, just block it at the air supply side hose at the air box with a plastic bottle cap or cork or fat bolt and secure it with electricians tape. Having it installed make it ready to activate if and when emission laws are enforced you will be ready, not buying one on ebay.
