How do you install headers pipes on 2004 HD roadking?

To install header pipes on a 2004 Harley-Davidson Road King, first, ensure the motorcycle is on a stable surface and the engine is cool. Remove the existing exhaust system by loosening the mounting bolts and disconnecting the heat shields. Install the new header pipes by aligning them with the cylinder heads and securing them with the provided gaskets and bolts. Finally, reattach any heat shields and ensure all connections are tight before starting the motorcycle to check for leaks.
