Every Harley has two exhaust pipes.
Harley-Davidson motorcycles are known for their V-twin engines. They are also known for being loud. However, Harley-Davidsons do not come from the factory quite so loud. Most owners replace the exhaust pipes with ones that increase the volume of the exhaust note to give their motorcycle that aggressive sound. Every Harley-Davidson motorcycle has two exhaust pipes, one connected to each engine cylinder.
1. Remove the two bolts that secure the exhaust header to the rear engine cylinder using a socket and ratchet. Complete this step with the front engine cylinder.
2. Trace the inside edge of exhaust pipe that connects to the rear engine cylinder until you locate the tail pipe mounting bracket. The bracket extends from the motorcycle frame and bolts to a bracket on the exhaust pipe. Depending on your model of Harley, the bracket connects to the pipe using a standard hex-bolt or an Allen-bolt. Hold the pipe in place while you remove the bolt and then place the pipe off to the side. Complete this step with the exhaust pipe that connected to the front cylinder engine.
3. Place a new exhaust pipe gasket onto the exhaust port on the rear cylinder. Place the rear pipe onto the gasket and secure it in place using the two bolts, socket and ratchet. Complete this step with the front cylinder.
4. Secure the tailpipe connected to the rear cylinder to the bracket on the frame using the bolt, socket and ratchet. Complete this step with the pipe connected to the front cylinder.
