What You’ll Need

Before you begin, gather all the necessary tools and materials. Having everything ready will make the installation process much smoother and more efficient. Here’s a comprehensive list:

Screamin’ Eagle Slip-On Mufflers: Make sure you have the correct mufflers for your specific Harley-Davidson model and year. Double-check the part number to ensure compatibility.

Step-by-Step Installation Guide

Now, let’s get into the step-by-step process of installing your new Screamin’ Eagle slip-on mufflers. Remember to take your time and follow each step carefully.

Remove the Old Mufflers:
1. Locate the exhaust clamps that secure the stock mufflers to the exhaust pipes. These are usually located near the connection points.
2. Loosen the exhaust clamps using a wrench or screwdriver. You might need to apply some penetrating oil if the clamps are rusted or stuck.
3. Carefully remove the stock mufflers from the exhaust pipes. You may need to wiggle and twist them to break the seal.
4. If the mufflers are difficult to remove, try tapping them gently with a rubber mallet. Avoid using excessive force, as you could damage the exhaust pipes.
5. Once the mufflers are detached, remove the exhaust gaskets from the exhaust pipe. These are usually located where the muffler connects to the exhaust pipe.
6. Inspect the exhaust pipes for any damage or corrosion. Clean the exhaust pipes with a wire brush or sandpaper if necessary.
Prepare the Exhaust Pipes:
1. If you’re replacing the exhaust gaskets (which is highly recommended), install the new gaskets on the exhaust pipes.
2. Apply a small amount of anti-seize compound to the threads of the bolts that will secure the new mufflers. This will make it easier to remove the bolts in the future.
Install the New Mufflers:
1. Carefully slide the new Screamin’ Eagle slip-on mufflers onto the exhaust pipes. Make sure they are aligned correctly.
2. Insert the new gaskets (if applicable) between the muffler and the exhaust pipe.
3. Attach the mounting hardware (clamps, bolts, etc.) to secure the mufflers to the exhaust pipes.
4. Tighten the exhaust clamps to the manufacturer’s recommended torque specifications. Use a torque wrench to ensure accuracy. Over-tightening can damage the clamps or the exhaust pipes. Under-tightening can cause leaks.
5. Double-check that the mufflers are securely attached and properly aligned.
Reinstall the Heat Shields (if applicable):
1. If your Screamin’ Eagle mufflers have heat shields, reinstall them now.
2. Align the heat shields with the mufflers and secure them using the provided hardware.
3. Make sure the heat shields are properly aligned and don’t interfere with any other components.
Final Checks and Reconnection:
1. Once the mufflers and heat shields (if equipped) are installed, double-check all bolts and clamps to ensure they are tightened to the correct torque specifications.
2. Reconnect the negative (-) battery cable.
3. Inspect the entire exhaust system for any leaks or loose connections.
Start the Engine and Check for Leaks:
1. Start your motorcycle and let it idle for a few minutes.
2. Listen for any exhaust leaks. You might hear a hissing sound if there are any leaks.
3. Check around the connections between the mufflers and the exhaust pipes.
4. If you detect any leaks, turn off the engine and tighten the clamps or bolts as needed.
5. Once you’re satisfied that there are no leaks, let the engine run for a longer period to allow the mufflers to heat up and the gaskets to fully seal.
6. After the engine has cooled down, recheck the tightness of all bolts and clamps.
Test Ride and Enjoy:
1. Take your bike for a short test ride. Listen to the sound of the new mufflers and make sure everything is running smoothly.
2. Check for any unusual noises or vibrations.
3. Enjoy the enhanced sound and performance of your Harley-Davidson!
