FMF Slip-On Exhaust: Make sure you have the correct model for your bike.
Wrench Set: Metric wrenches are essential. Include a range of sizes.
Socket Set: A good socket set with extensions will be needed.
Torque Wrench: Crucial for tightening bolts to the correct specifications (highly recommended).
Screwdrivers: Both Phillips head and flathead screwdrivers.
Penetrating Oil: For loosening stubborn bolts (like PB Blaster).
Anti-Seize Compound: Prevents bolts from seizing in the future.
Gloves: Protect your hands.
Safety Glasses: Protect your eyes.
Work Stand: To stabilize your motorcycle.
Shop Towels: For cleaning and wiping.
Owner’s Manual: Your bike’s manual is an invaluable resource.
Optional: Exhaust Spring Puller (makes spring removal easier).

Safety First

Your safety is the most important thing. Always prioritize safety during this process. Here are some essential safety precautions:

Work in a well-ventilated area: Exhaust fumes can be dangerous.
Wear safety glasses: Protect your eyes from debris.
Wear gloves: Protect your hands from sharp edges and heat.

Step 1: Prepare Your Motorcycle

Before you start, prepare your bike for the installation:

Secure the motorcycle: Use a work stand to lift and stabilize your motorcycle. Ensure it is level and stable.
Locate the exhaust: Identify the stock exhaust system, specifically the slip-on portion that you will be replacing.
Gather tools: Have all your tools and the FMF exhaust ready.
Read the instructions: Review the FMF exhaust’s instructions to familiarize yourself with the specific details for your model.

Step 2: Remove the Old Exhaust

This is where you remove the existing slip-on exhaust. Take your time and be careful:

Loosen the clamp(s): Locate the clamp(s) that secure the stock slip-on exhaust to the header pipe. Use a wrench or screwdriver to loosen the clamp(s). Penetrating oil can help if the clamp is stuck.
Remove the springs (if applicable): Some exhaust systems use springs to connect the slip-on to the mid-pipe or header. Use an exhaust spring puller, if you have one, to remove these springs. If you don’t have a puller, a small hook tool or pliers can work. Be careful not to damage the springs.
Detach the exhaust: Gently twist and pull the old slip-on exhaust to remove it from the header pipe or mid-pipe. It might be stuck due to carbon buildup. You might need to tap it gently with a rubber mallet.
Clean the mating surfaces: Use a shop towel to clean the mating surfaces of the header pipe and the new exhaust. This ensures a good seal.
Inspect the gaskets (if applicable): Check the condition of any gaskets. Replace them if they are damaged or worn.

Step 3: Install the Fmf Slip-on Exhaust

Now it’s time to install your new FMF slip-on exhaust:

Prepare the new exhaust: Take the FMF slip-on exhaust and any included hardware out of the box.
Install the new exhaust: Carefully slide the FMF slip-on exhaust onto the header pipe or mid-pipe. Make sure it is fully seated.
Attach the springs (if applicable): If your system uses springs, attach them now. Use an exhaust spring puller or pliers. Ensure the springs are securely connected.
Install the clamp(s): Position the clamp(s) over the connection point and tighten them. Don’t overtighten the clamp(s) initially; leave them slightly loose for adjustment.
Align the exhaust: Adjust the position of the exhaust to ensure it is aligned correctly with the bike’s bodywork. Make sure it doesn’t touch any part of the bike that could be damaged by heat.
Tighten the clamp(s): Once you’re satisfied with the alignment, tighten the clamp(s) to the manufacturer’s recommended torque specifications. If you don’t have a torque wrench, tighten the clamp(s) firmly but not excessively.
Install any included hardware: Follow the FMF instructions to install any other included hardware, such as brackets or mounting hardware.

Step 4: Final Checks and Adjustments

Before you start your bike, perform some final checks: (See Also: Will Two Brothers Slip On Exhaust Work For Rebel 300 )

Double-check all connections: Ensure all clamps, bolts, and springs are securely in place.
Verify clearances: Make sure the exhaust is not touching any part of the bike, such as the swingarm, bodywork, or tires.
Check for leaks: Visually inspect the connections for any potential leaks.
Torque check (if applicable): If you have a torque wrench, double-check that all bolts are tightened to the correct specifications.

Step 5: Start Your Motorcycle and Listen

Now, it’s time to fire up your bike and enjoy the new sound:

Start the engine: Start your motorcycle and let it idle for a few minutes.
Check for leaks: Listen carefully for any exhaust leaks. If you hear a leak, tighten the clamps or connections.
Listen to the sound: Enjoy the new, improved sound of your FMF slip-on exhaust!
Check for performance: Take your bike for a short ride to feel the difference in performance.
Re-torque after riding: After your first ride, let the exhaust cool down and re-torque the bolts and clamps. This is crucial as heat cycles can cause them to loosen.

Tips for a Smooth Installation

Here are some extra tips to help you with the installation:

Use penetrating oil: If bolts are stuck, apply penetrating oil and let it sit for a while before trying to loosen them.
Protect your bike: Use shop towels or tape to protect the bodywork from scratches.
Take photos: Take pictures of each step as you remove the old exhaust. This can be helpful if you get stuck.
Don’t force anything: If something doesn’t fit, don’t force it. Double-check the instructions and ensure you have the correct parts.
Work in a clean environment: A clean workspace will make it easier to find small parts and prevent any dirt from entering the exhaust system.
Consult the manual: Always refer to your bike’s service manual and the FMF exhaust instructions.
Take breaks: If you feel frustrated, take a break. Come back to the project with a fresh perspective.
Have a friend help: An extra set of hands can be very helpful, especially when aligning the exhaust or tightening bolts.

Troubleshooting Common Issues

Sometimes, things don’t go perfectly. Here are some common issues and how to resolve them:

Exhaust leaks: If you hear a hissing sound, you have an exhaust leak. Check the connections, tighten the clamps, and ensure the gaskets are in good condition. Replace any damaged gaskets.
Difficult to remove bolts: Use penetrating oil and let it soak. Use the correct size wrench or socket. If a bolt is stripped, you may need to use a bolt extractor.
Exhaust not aligning properly: Loosen the clamps and adjust the position of the exhaust. Ensure it is not touching any part of the bike.
Exhaust too loud: Make sure you have installed any included baffles or inserts. Check the exhaust for any damage.
Performance issues: If you experience performance issues after installation, check for exhaust leaks and ensure the exhaust is properly installed. You may need to re-jet or remap your bike’s fuel injection system if you have made significant changes to the exhaust.
