How to Put Pipes on a Harley-Davidson
New exhaust pipes on a Harley-Davidson motorcycle are often the first performance upgrade by an owner. Depending on what you choose, new pipes can increase gas mileage and power. For some riders, performance is secondary to style, and different pipes can substantially change the look of a Harley. You have a tremendous selection of exhaust pipes and mufflers to choose from. It is important that you match the engine specs, the air intake and the exhaust for maximum performance of your Harley. The right combination is well worth the effort.
- Socket set
- Crush gasket
- Exhaust pipes
Park your Harley on level ground. Allow the engine to cool down. Use a socket with an extension to remove the nuts holding the exhaust pipe to the cylinder head. There are two nuts and washers for the front and rear exhaust.
Remove the locknut and the bolt holding the pipes to the rear support bracket. The rear support location varies according to the model and the exhaust pipe setup.
Remove the exhaust pipes by carefully sliding them off the cylinder head studs.
Remove the exhaust crush gasket from the exhaust port. Carefully clean the port with a rag.
Insert the new crush gasket into the exhaust port.
Slide the new exhaust pipes onto the cylinder head studs and finger-tighten the nuts in place.
Line up the pipes with the rear bracket and install the bolt and locknut. Do not tighten.
Align the pipes carefully and tighten the nuts at the cylinder head.
Tighten the support bracket locknut.
