Step-by-Step Installation Guide

Follow these steps carefully to ensure a successful installation of your new slip-on exhaust.

Step 1: Preparation and Safety

Safety is paramount. Before you start, ensure the motorcycle is stable and the engine is cool. Working on a hot exhaust system can lead to burns. Here’s what to do:

Park on a Level Surface: Use a jack or wheel chocks to stabilize the motorcycle.
Allow the Engine to Cool: Wait at least 30 minutes after riding to allow the exhaust system to cool down.
Wear Safety Gear: Put on your safety glasses and gloves.

Step 2: Removing the Old Exhaust

This involves carefully removing the existing slip-on mufflers. Take your time and be patient, especially if the bolts are corroded. (See Also: Won Hundred Willow Slip On Sneakers )

Locate the Exhaust Bolts: Identify the bolts that secure the slip-on mufflers to the head pipes. Usually, there will be two or three bolts per muffler.
Apply Penetrating Oil: If the bolts look rusty or corroded, spray them with penetrating oil and let it sit for a few minutes. This can significantly ease removal.
Loosen the Bolts: Use the appropriate wrench or socket to loosen the bolts. Be careful not to strip them. If they are difficult to remove, try tapping the wrench with a hammer to help break them free.
Remove the Mufflers: Once the bolts are loose, carefully remove the mufflers. They might be a bit snug, so gently wiggle them until they come free from the head pipes.
Inspect the Gaskets: Check the condition of the exhaust gaskets where the mufflers connect to the head pipes. If they’re worn or damaged, replace them with new ones.

Step 3: Preparing the New Slip-on Exhaust

Before installing the new mufflers, ensure everything is ready to go. This typically includes:

Inspect the New Mufflers: Make sure all the necessary hardware is included and that the mufflers are in good condition.
Apply Anti-Seize Compound: Lightly apply anti-seize compound to the threads of the new bolts. This will prevent corrosion and make future removal easier.
Install New Gaskets (If Needed): If you’re replacing the gaskets, install them now on the head pipes.

Step 4: Installing the New Slip-on Exhaust

Carefully attach the new mufflers to the head pipes. This is where precision and care are essential.

Position the Mufflers: Align the new mufflers with the head pipes.
Insert the Mufflers: Carefully slide the slip-on mufflers onto the head pipes. Make sure they are fully seated.
Install the Bolts: Insert the bolts and hand-tighten them. Do not fully tighten them at this stage.
Adjust Alignment: Ensure the mufflers are aligned correctly and that they are positioned as desired.

Step 5: Tightening the Bolts

This is a crucial step for a secure and leak-free exhaust system. Use a torque wrench for accurate tightening.

Torque to Spec: Use a torque wrench to tighten the bolts to the manufacturer’s recommended torque specifications. These specifications can usually be found in the instructions that came with your slip-on exhausts or in your Harley-Davidson service manual.
Tighten in Stages: Tighten the bolts in a crisscross pattern, gradually increasing the torque in stages. This helps ensure even pressure and prevents leaks.
Double-Check: After tightening, double-check all bolts to make sure they are properly torqued.

Step 6: Final Checks and Startup

Before taking your Road Glide out for a ride, perform a final inspection and start the engine.

Inspect for Leaks: Visually inspect all connections for any signs of exhaust leaks.
Start the Engine: Start the engine and let it run for a few minutes. Listen for any unusual noises or leaks.
Check Again: After the engine has warmed up, re-check all bolts to ensure they are still tight. The heat can sometimes cause bolts to loosen slightly.
Road Test: Take your Road Glide for a short test ride to ensure everything is working correctly and that you are satisfied with the sound and performance.

Additional Tips and Considerations

Here are some extra tips to help you with the installation and ensure the best possible results:

Read the Instructions: Always carefully read the instructions provided with your new slip-on exhaust system. These instructions often contain specific details and recommendations for your particular model.
Use the Right Tools: Using the correct tools is crucial. Avoid using the wrong size wrench or socket, as this can damage the bolts and hardware.
Be Patient: Don’t rush the process. Take your time and work carefully. Rushing can lead to mistakes and potential damage.
Protect Your Paint: Be careful not to scratch or damage the paint on your motorcycle during the installation. Consider using painter’s tape to protect vulnerable areas.
