To use this front pipe, first, make sure your vehicle is a 2022+ Honda Civic Si or 2022+ Integra. You can pair it with an OEM or aftermarket downpipe for better results, but don't try to use it with the factory exhaust system as it's not compatible. When installing, follow the standard installation procedures for exhaust parts. As for maintenance, regularly check the connections to make sure they're tight. If you notice any signs of rust or damage, clean or replace the pipe as needed. This will help keep your vehicle running smoothly and sounding great.
