What You’ll Need
Before you begin, gather all the necessary tools and materials. This will make the installation process much smoother and prevent any frustrating delays.
- Two Brothers Racing Slip-On Exhaust Kit: Make sure you have the correct model for your motorcycle.
- Socket Set: Including various sizes, both metric and possibly imperial depending on your bike.
- Wrench Set: Open-end and box-end wrenches, again in both metric and possibly imperial.
- Torque Wrench: Essential for tightening bolts to the correct specifications.
- Allen Wrenches/Hex Keys: Often included with the exhaust kit, but have a set handy.
- Penetrating Oil (e.g., PB Blaster or Liquid Wrench): For loosening stubborn bolts.
- Gloves: Protect your hands.
- Safety Glasses: Protect your eyes.
- Work Stand or Motorcycle Lift: To keep your bike stable.
- Rags or Shop Towels: For cleaning and wiping.
- Anti-Seize Compound: To prevent future corrosion and make removal easier.
- Optional: Exhaust Spring Puller Tool (makes removing springs easier).
Step-by-Step Installation Guide
Now, let’s dive into the step-by-step process of installing your Two Brothers slip-on exhaust. Remember to consult your motorcycle’s service manual for specific torque specifications and any model-specific instructions.
Step 1: Preparation Is Key
Before you start, ensure your motorcycle is cool. Working on a hot exhaust system can lead to burns. Place your bike on a stable work stand or lift. This will make the process easier and safer. (See Also: Won Hundred Willow Slip On Sneakers )
Step 2: Remove the Old Exhaust
- Locate the Stock Exhaust: Identify the section of the exhaust system you’ll be replacing. Typically, this is the muffler (the part that’s most visible) or the slip-on portion.
- Loosen and Remove the Mounting Hardware: Using the appropriate tools (sockets or wrenches), loosen and remove the bolts or clamps that secure the stock exhaust to the motorcycle’s frame and to the exhaust header pipe. Penetrating oil might be necessary if the bolts are corroded. Be careful not to strip any bolts.
- Remove the Exhaust: Carefully slide the stock muffler off the header pipe. You might need to wiggle it or gently tap it with a rubber mallet if it’s stuck. If the exhaust is held on by springs, use the exhaust spring puller tool (if you have one) or carefully remove them with pliers.
- Clean the Header Pipe: After removing the old exhaust, clean the header pipe where the new slip-on will connect. Remove any old gasket material or debris.
Step 3: Install the New Two Brothers Slip-on Exhaust
- Prepare the New Exhaust: Unpack the Two Brothers exhaust kit and identify all the components. Ensure you have everything you need.
- Install the Mounting Bracket(s): Attach the mounting bracket(s) to the new muffler using the provided hardware.
- Apply Anti-Seize Compound: Apply a small amount of anti-seize compound to the threads of the bolts that will secure the exhaust. This will prevent corrosion and make future removal easier.
- Slide the Slip-On onto the Header Pipe: Carefully slide the slip-on exhaust onto the header pipe. Make sure it’s fully seated and aligned properly.
- Secure the Exhaust: Attach the exhaust to the frame using the mounting bracket(s) and hardware. Don’t tighten the bolts completely at this stage; leave them slightly loose so you can adjust the position.
- Connect the Spring(s) (If Applicable): If your Two Brothers exhaust uses springs to connect to the header pipe, use the exhaust spring puller tool or pliers to securely attach them.
Step 4: Alignment and Tightening
- Align the Exhaust: Carefully align the new exhaust to ensure it’s positioned correctly and doesn’t interfere with any other parts of the motorcycle, like the swingarm, rear tire, or bodywork.
- Tighten the Hardware: Using a torque wrench, tighten all the bolts and clamps to the manufacturer’s specified torque. Refer to your motorcycle’s service manual or the Two Brothers exhaust instructions for these specifications. Overtightening can damage the exhaust or the motorcycle’s components.
Step 5: Final Checks and Startup
- Double-Check Everything: Before starting the engine, double-check all the bolts, clamps, and springs to ensure they are securely fastened. Make sure no tools or parts are left behind.
- Start the Engine: Start the motorcycle and listen for any exhaust leaks. If you hear any hissing sounds, it indicates a leak. Check all the connections and tighten the bolts or clamps as needed.
- Check for Leaks Again: Once the engine is warm, check again for any leaks.
- Inspect for Interference: After the engine has run for a few minutes, inspect the exhaust system for any signs of interference with the motorcycle’s components.
- Enjoy the Ride!: Once you’re satisfied with the installation, take your motorcycle for a test ride and enjoy the new sound and performance of your Two Brothers slip-on exhaust!
Important Considerations and Tips
- Gaskets: Some exhaust systems require new gaskets. If your kit includes one, make sure to install it correctly.
- Torque Specifications: Always use a torque wrench and adhere to the manufacturer’s torque specifications. Over-tightening can damage threads, while under-tightening can lead to leaks and vibration.
- Rust and Corrosion: If you live in an area with a lot of road salt or humidity, consider using a high-temperature exhaust sealant at the joints to prevent corrosion and leaks.
- Heat Shields: Make sure to reinstall any heat shields that came with your original exhaust system to protect yourself and the motorcycle’s components from the heat.
- Break-In Period: Some exhaust systems may require a break-in period. Refer to the Two Brothers Racing instructions for any specific recommendations.
- Decibel Levels: Be mindful of local noise regulations. Some exhaust systems are louder than stock and may not be street-legal in all areas.
- Dyno Tuning (Optional): While a slip-on exhaust usually doesn’t require it, a dyno tune can optimize your bike’s performance, especially if you’ve made other modifications.
- Safety First: Always wear appropriate safety gear, including gloves, eye protection, and a helmet. Work in a well-ventilated area.
- Patience and Persistence: Installing an exhaust can sometimes be challenging. Don’t get discouraged if you encounter difficulties. Take your time, double-check your work, and consult the Two Brothers Racing instructions or online resources if needed.
Troubleshooting Common Issues
Even with careful planning, you might encounter some issues during the installation. Here are some common problems and how to address them:
Exhaust Leaks
Problem: You hear a hissing sound coming from the exhaust joints. This indicates a leak.
Solution:
- Check Connections: Ensure all the connections are tight and properly sealed.
- Inspect Gaskets: If your exhaust uses gaskets, make sure they are in good condition and installed correctly. Replace them if necessary.
- Tighten Clamps: Tighten the exhaust clamps to the recommended torque specification.
- Use Exhaust Sealant: If the leak persists, consider using high-temperature exhaust sealant at the joints.
