Using your DC Sports Ceramic Coated Header is straightforward. First, make sure your vehicle is turned off and has cooled down. Install the header following the included instructions. It's important to double - check all connections to ensure they're tight. When driving, you'll notice improved performance right away. As for maintenance, keep an eye on the ceramic coating. If you live in an area with harsh road conditions, give the header a visual inspection every few months. Avoid using abrasive cleaners on the coating. Just wash it gently with mild soap and water to keep it in good shape. If you ever have any issues, refer to the product manual or contact our customer service.
