Using your DC Sports Ceramic Header is straightforward. Just install it in place of your stock header following the included instructions. When driving, you'll notice better performance right away. As for maintenance, keep an eye on the ceramic coating. If it starts to show signs of wear, it might need recoating. Avoid hitting the header on rough terrain as it could damage the coating or the header itself. Also, regularly check the welds and connections to make sure they're tight. If you live in an area with a lot of road salt, give the header a good rinse every once in a while to prevent corrosion. That's all there is to it to keep your header in top shape and your car running great.
