Using this exhaust system is straightforward. First, make sure your vehicle is a 2008 - 2010 Ford F - Series with a 6.4L Powerstroke engine. If your truck has a suspension lift or airbags, you may need to make some minor modifications. The exhaust system is designed to mount to the original hangers, so installation should be easy. Just follow the included instructions. As for maintenance, regularly check the exhaust for any signs of damage or loose connections. If you chose the aluminized steel option, it may rust over time, so you might want to clean it and apply a protective coating. For the stainless steel option, it's more resistant to corrosion but still needs a periodic check. Enjoy the improved performance and great sound this exhaust system brings to your vehicle.
