This guide focuses specifically on installing a Cobra slip-on exhaust, which typically replaces the stock muffler while retaining the original head pipes. This makes the installation easier than a full exhaust system replacement. Let’s get started!
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 list of what you’ll need:
- Cobra Slip-On Exhaust: Obviously! Make sure you have the correct model for your Yamaha Stryker.
- Socket Set: A good quality socket set, including both metric and standard sizes, is essential.
- Wrench Set: A combination wrench set, again in both metric and standard sizes, is helpful.
- Torque Wrench: Crucial for tightening bolts to the correct specifications. Over-tightening can damage threads, while under-tightening can lead to leaks.
- Screwdrivers: Both Phillips head and flathead screwdrivers will be needed.
- Penetrating Oil (e.g., PB Blaster): This can be helpful for loosening stubborn bolts.
- Anti-Seize Compound: Prevents the exhaust bolts from seizing in the future.
- Gloves: Protect your hands.
- Safety Glasses: Protect your eyes.
- Jack or Motorcycle Lift (Optional): Makes the bike more stable and easier to work on.
- Wheel Chocks (Optional): For added stability.
- Shop Rags: For cleaning and wiping up spills.
- Owner’s Manual: Refer to your Stryker’s owner’s manual for torque specifications and other relevant information.
Step-by-Step Installation Guide
Now, let’s get into the installation process. Follow these steps carefully, and you’ll have your new Cobra slip-on exhaust installed in no time.
Step 1: Preparation Is Key
Before you start, ensure your Yamaha Stryker is cool. Never work on a hot exhaust system. Place the bike on a level surface and secure it. If you have a jack or motorcycle lift, use it to raise the bike for easier access. If not, make sure the bike is stable and won’t tip over. Use wheel chocks if necessary.

Step 2: Removing the Stock Exhaust
This is where you’ll remove the existing exhaust system. Here’s how:
- Locate the Exhaust Bolts: Find the bolts that secure the stock muffler to the exhaust pipe. These are usually located near the connection point.
- Apply Penetrating Oil (If Needed): If the bolts look rusty or corroded, apply penetrating oil and let it soak for a few minutes. This will make them easier to remove.
- Loosen the Bolts: Using a socket or wrench, carefully loosen and remove the bolts. Be patient, and don’t force them. If they are difficult to remove, apply more penetrating oil and try again.
- Remove the Stock Muffler: Once the bolts are removed, carefully detach the stock muffler from the exhaust pipe. You may need to wiggle it or gently tap it with a rubber mallet to break it free.
- Remove the Muffler Bracket (If Applicable): Some stock mufflers have a bracket that attaches to the frame. Remove this bracket as well.
Step 3: Installing the Cobra Slip-on Exhaust
Now, let’s install the new Cobra exhaust. Follow these steps:
- Prepare the New Exhaust: Take the Cobra slip-on exhaust out of the box and familiarize yourself with its components.
- Install the Mounting Bracket (If Applicable): Some Cobra exhausts require you to install a mounting bracket to the frame. Follow the instructions provided with your exhaust.
- Attach the Slip-On to the Exhaust Pipe: Carefully slide the Cobra slip-on exhaust onto the exhaust pipe. Make sure it aligns correctly.
- Insert the Mounting Hardware: Insert the bolts provided with the Cobra exhaust. Ensure the exhaust is properly seated.
- Tighten the Bolts: Using a torque wrench, tighten the bolts to the manufacturer’s specified torque. Refer to the instructions that came with your Cobra exhaust. If no torque spec is provided, consult your Stryker’s service manual or use a general guideline for similar-sized bolts. Be careful not to overtighten.
- Install the Muffler Clamp (If Applicable): Some Cobra exhausts use a clamp to secure the slip-on to the exhaust pipe. Install this clamp and tighten it to the specified torque.
- Check for Alignment: Make sure the exhaust is aligned correctly and doesn’t interfere with any other components on your bike.
Step 4: Final Checks and Finishing Touches
Before you start your engine, perform these final checks:
- Inspect all connections: Ensure all bolts are tightened to the correct specifications.
- Check for Leaks: Visually inspect all connections for any signs of exhaust leaks.
- Clean Up: Wipe down the exhaust with a clean rag to remove any fingerprints or smudges.
- Reinstall any removed components: Ensure that you have not forgotten to re-install any parts that were removed during the process.
Step 5: Starting the Engine and Checking for Leaks
Once you are confident that everything is installed correctly, start the engine and let it run for a few minutes. Listen for any exhaust leaks. If you hear any hissing sounds, it indicates a leak. Check the connections and tighten the bolts if necessary.
Step 6: The Test Ride
Take your Yamaha Stryker for a test ride. Pay attention to the sound and performance of the new exhaust. Make sure the exhaust doesn’t interfere with your riding and that everything feels secure. After the ride, check the exhaust again for any leaks or loose bolts. Enjoy the enhanced sound and performance of your new Cobra slip-on exhaust!

Important Considerations and Tips
Torque Specifications
Always use a torque wrench and tighten the bolts to the manufacturer’s specifications. Over-tightening or under-tightening can lead to problems. If you don’t have access to the exact specifications, consult your Stryker’s service manual or use a general guideline based on the bolt size and material. Remember that a properly torqued bolt is crucial for a safe and reliable installation.
Anti-Seize Compound
Applying anti-seize compound to the exhaust bolts before installation will help prevent them from seizing in the future. This will make it much easier to remove the exhaust in the future if you need to.
Dealing with Stubborn Bolts
If you encounter a stubborn bolt that won’t budge, don’t force it. Apply penetrating oil and let it soak for a while. You can also try using a breaker bar or a socket with a longer handle for more leverage. If the bolt still won’t come loose, consider using a heat gun to gently heat the area around the bolt. Be careful not to overheat the surrounding components.
Safety Precautions
Always wear safety glasses and gloves while working on your motorcycle. Work in a well-ventilated area, especially when using penetrating oil or other chemicals. Make sure the bike is stable and secure before you start working on it. Never work on a hot exhaust system. Allow the exhaust to cool down completely before starting the installation.
Troubleshooting Common Issues
Here are some common issues you might encounter and how to address them: (See Also: Will You Lose Low End With M4 Slip On Fz07 )
- Exhaust Leaks: Check all connections and tighten the bolts. If the leak persists, you may need to replace the exhaust gasket or use a high-temperature sealant.
- Difficulty Removing Bolts: Apply penetrating oil and let it soak. Use a breaker bar or a socket with a longer handle for more leverage.
- Exhaust Doesn’t Fit Properly: Double-check that you have the correct exhaust model for your Yamaha Stryker. Make sure you are following the installation instructions carefully.
- Sound is Too Loud: Some slip-on exhausts can be quite loud. If the sound is too loud for your liking, consider adding a baffle or using a quieter exhaust system.
Maintaining Your New Exhaust
Once you’ve installed your Cobra slip-on exhaust, proper maintenance will help keep it looking and performing its best. Here are some tips:
- Regular Cleaning: Clean your exhaust regularly with a mild soap and water solution. Avoid using abrasive cleaners or steel wool, as these can scratch the finish.
- Inspect for Damage: Periodically inspect your exhaust for any signs of damage, such as dents, cracks, or corrosion.
- Check for Leaks: Regularly check the connections for any exhaust leaks. Tighten the bolts as needed.
- Protect from the Elements: If you live in an area with harsh weather conditions, consider using a protective coating or cover to help protect your exhaust from corrosion.
- Follow Manufacturer’s Recommendations: Always follow the manufacturer’s recommendations for maintenance and care.
