How to Install Screamin Eagle Pipes
The trouble with stock Harley-Davidson exhausts, or pipes, is that they are intentionally designed to inhibit the respiration of the engine. Exhaust gases are stopped, or obturated, from escaping into the atmosphere. The result is a big engine that chokes, gags and performs like a little engine. Consequently, a market in replacement exhausts thrives. Harleys brand of replacement parts to make the factory engine run the way it should is the Screamin Eagle performance line. Perhaps you bought only the Screamin Eagle mufflers, but replacing the entire exhaust only involves turning a few more nuts and bolts.

Remove all heat shields by completely loosening the worm clamps that hold them to the exhaust pipes with a flat-head screwdriver.
2Loosen and remove the two flange nuts that secure the front and rear exhaust pipes to the cylinder heads with a socket wrench and a hex socket, if you intend to replace the complete exhaust. Slide the exhaust flange and retaining ring off the cylinder head studs.
3Loosen and remove the two oxygen sensors that bolt into your exhaust near the transmission cover using an open end wrench.
4Loosen and remove the two nuts and bolts that secure the front and rear exhaust pipes to the frame bracket using an open end wrench.
5Remove the complete exhaust assembly from the motorcycle. Remove the exhaust port gaskets from the exhaust ports in the cylinder heads.
6Loosen both the muffler clamps that fasten the mufflers to the header pipes using a socket wrench and hex socket. Remove both mufflers with the interconnect tube (if applicable) from the exhaust pipes.
7Remove both mufflers from the interconnect tube using a socket wrench and hex socket. Remove and discard the interconnect tube gaskets.
8Bolt the new mufflers to the interconnect tube (if applicable) using replacement gaskets and a socket wrench and hex socket. Connect the mufflers to the new or replacement exhaust pipes using the old mufflers clamps.
9Replace the exhaust port gaskets in the exhaust ports in the cylinder head.
10Tighten the muffler clamps with a socket wrench and hex socket. Connect the front and rear exhaust pipes to the frame bracket using an open end wrench and the hardware you removed earlier
11Coat the thread of the two oxygen sensors with Teflon paste. Install the oxygen sensors in the front and rear exhaust pipes. Tighten with an open end wrench.
12Reconnect the exhaust pipes to the exhaust ports using the flanges, retaining rings and nuts you removed earlier. Tighten the nuts on the exhaust studs with a socket wrench and hex socket.
13Replace the heat shields on the exhaust. Refasten the worm clamps using a flat-head screwdriver.

How to Clamp Exhaust Pipes Together
The exhaust system of your vehicle directs exhaust fumes from the engine away from the passenger compartment of the vehicle. Exhaust clamps not only hold the exhaust pipe together, but also ensure your safety by keeping dangerous carbon monoxide from entering your vehicle. When carbon monoxide accumulates in your vehicle, it displaces oxygen and in high concentrations can cause you to pass out and possibly die from asphyxiation. Theore, it is vital that you properly install the exhaust clamps to eliminate carbon monoxide from entering your vehicle.

Put on your safety glasses and work gloves.
2Disassemble the exhaust clamp by loosening and then removing the hex nuts from the U-bolt.
3Place the saddle on the top of the exhaust pipe connection, slide the U-bolt into the saddle and thread one hex nut on each leg of the U-bolt. Do not tighten the hex nuts, as this will hinder your ability to perform the next step.
4Apply pressure to the exhaust pipe connection to ensure that the connection is fully seated.
5Select a socket from the socket set that matches the size of the hex nuts, and attach it to the 3/8-inch ratchet.
6Set the ratchet to tighten.
7Slide the socket onto one of the hex nuts and tighten the nut until it is tight.
8Repeat the process to tighten the other hex nut.
9Check the first hex nut that you tightened with the ratchet for tightness. If the nut is loose, re-tighten it. You should notice the exhaust pipe pulling in under the pressure of the exhaust clamp.
10Pull on the exhaust clamp to ensure that it is tight, and then perform the same steps on any other exhaust clamps you need to install.
