Notes	***Optional Frontpipe Sold Separately (Part No. 145-H003) Before completing the installation of the exhaust system with the factory OEM Valve Motor System, follow these steps: Uninstall the OE Valve Motor: Remove the OE Valve motor from the factory exhaust and disconnect it from the harness connected to the vehicle. Reset the Valve Motor: Prior to mounting the valve motor on the A'PEXi N1-X Exhaust System, ensure to plug the Valve Motor separately to initiate a factory reset position. This process typically takes around 5-10 seconds to automatically rewind to the reset position. Notably, this reset can be performed without the car being turned on. Reinstall the Valve Motor: Once the Valve Motor has completed its self-reset, remount it onto the bracket and proceed to install both the Valve Motor and the bracket onto the N1-X exhaust system. Following these steps ensures proper installation and functionality of the exhaust system with the Valve Motor System.
