Using your DC Sports Ceramic Header is easy. Just install it in place of your old header following the standard installation procedures for your 99 - 00 Honda Civic Si or 94 - 97 DelSol VTEC. Make sure all connections are tight to avoid any exhaust leaks. When it comes to maintenance, regularly check the header for any signs of damage or loose connections. If you notice any corrosion, you can clean the ceramic coating gently with a mild soap and water solution. Avoid using harsh chemicals as they can damage the coating. Also, be careful when driving on rough roads to prevent physical damage to the header. This header is built to last, but a little care will keep it performing at its best for a long time.
