The 12oclock Labs EXUP Emulator is used in place of the stock exhaust servo motor when you replace the stock exhaust with an aftermarket exhaust system. The microprocessor controlled EXUP, emulates the exact characteristics of the stock exhaust servo motor and its motor delay sweeps, keeping the ECU from displaying the dreaded check engine light. Weight is less than 1/2 an ounce and it is a direct plug and play replacement.
