What You’ll Need

Before you even think about touching your bike, make sure you have everything you need. This will save you time and frustration. Here’s a comprehensive list:

Two Brothers Racing Slip-On Exhaust Kit: Obviously, you’ll need the exhaust kit itself. Make sure it’s specifically for your Ninja 250R model year.
Socket Set: A decent set of sockets is essential. You’ll need various sizes, including metric ones. A 10mm and 12mm socket are commonly used.
Wrench Set: Similar to sockets, a set of wrenches is crucial. Box-end wrenches are often preferred.
Torque Wrench: This is important for tightening bolts to the correct specifications. Over-tightening can damage threads, while under-tightening can lead to leaks and vibration.
Allen Wrenches (Hex Keys): The TBR exhaust likely uses Allen head bolts. Make sure you have a set.
Penetrating Oil (e.g., PB Blaster): This can be helpful if any of the stock exhaust bolts are stubborn.
Gloves: Protect your hands.
Safety Glasses: Always protect your eyes.
Jack or Lift (Optional, but recommended): Makes accessing the exhaust easier.
WD-40 or similar lubricant: For easier removal of the old exhaust and installation of the new one.
Shop Rags: For cleaning up spills and wiping down parts.
Owner’s Manual for your Ninja 250R: Refer to it for torque specifications.

Step-by-Step Installation Guide

Now, let’s get down to the actual installation. Follow these steps carefully. (See Also: Do Vans Slip On Stretch )

Step 1: Preparation Is Key

Before you begin, make sure your Ninja 250R is cool. Working on a hot exhaust is a recipe for burns! Place your bike on a stable surface. If you have a bike lift, use it to raise the rear of the bike. This will give you better access. Gather all the tools and parts listed above and have them within easy reach.

Step 2: Removing the Stock Exhaust

This is where the fun begins! We’re going to remove the old exhaust. Here’s the process:

Locate the Exhaust Components: Identify the stock exhaust system. The slip-on exhaust replaces the muffler section, which is typically the last part of the exhaust system.
Loosen the Clamp(s): There’s usually a clamp connecting the muffler to the mid-pipe (the section that connects to the engine). Use a socket or wrench to loosen the bolt on this clamp. Sometimes, these clamps can be a bit corroded. If you’re having trouble, apply some penetrating oil and let it sit for a few minutes.
Remove the Muffler: Carefully wiggle and pull the stock muffler off the mid-pipe. It might be a tight fit. You might need to twist and rotate it while pulling. WD-40 or a similar lubricant can help here. Be careful not to damage the mid-pipe.
Remove the Hanger Bolt(s): The muffler is also usually held in place by a bolt or bolts that attach it to the bike’s frame. Remove these bolts.
Detach the Exhaust from the Header (If Necessary): Some Ninja 250R models may require you to disconnect the exhaust from the header. This may involve loosening more clamps or bolts. Consult your owner’s manual if needed.
Inspect the Components: Once the old exhaust is off, take a look at the mid-pipe. Clean it if necessary. Check for any damage.

Step 3: Installing the Two Brothers Racing Slip-on Exhaust

Now it’s time to install the new, shiny exhaust! Here’s how:

Prepare the TBR Exhaust: Unpack your new TBR exhaust. Familiarize yourself with the components. You should have the muffler, a clamp, and any necessary mounting hardware.
Attach the Muffler to the Mid-Pipe: Slide the TBR muffler onto the mid-pipe. Make sure it’s seated properly.
Install the Clamp: Place the clamp over the connection between the muffler and the mid-pipe. Tighten the clamp bolt, but don’t tighten it fully yet. You’ll want some play for adjustment.
Mount the Exhaust to the Frame: Use the provided hardware (or the stock hardware, if applicable) to attach the muffler to the bike’s frame.
Align and Adjust: Make sure the exhaust is aligned properly and that it’s not touching any other parts of the bike. Adjust the position of the muffler as needed.
Tighten All Bolts and Clamps: Once you’re happy with the alignment, tighten all bolts and clamps to the manufacturer’s recommended torque specifications. Use your torque wrench for this. Refer to your Ninja 250R owner’s manual for these specs. Don’t overtighten!

Step 4: Final Checks and Startup

You’re almost there! Before you start the bike, do a thorough check: (See Also: How Should Slip On Work Boots Fit )

Double-check all bolts and clamps: Make sure everything is tight.
Inspect the exhaust for leaks: Look for gaps or anything that doesn’t look right.
Remove any tools or materials: Make sure you haven’t left anything behind.

Now, start your Ninja 250R. Listen for any exhaust leaks. If you hear a hissing sound, you might have a leak at a connection. If this happens, tighten the clamp or bolt in that area. Let the bike run for a few minutes to allow the exhaust to heat up and settle in. Check again for leaks after the exhaust has warmed up.

Step 5: Finishing Touches

With the exhaust installed and running smoothly, there are a few finishing touches to consider:

Clean Up: Wipe down the new exhaust with a clean rag.
Check the Installation After Riding: After riding your bike for a short distance, check all bolts and clamps again to ensure they are still tight. Vibration can sometimes cause them to loosen.
Break-In Period: While not always necessary, some exhaust manufacturers recommend a break-in period. Refer to the Two Brothers Racing instructions for any specific recommendations.
Enjoy the Ride!: You’ve successfully installed your new TBR slip-on exhaust! Enjoy the improved sound and (potentially) performance of your Ninja 250R!

Troubleshooting Common Issues

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

Exhaust Leaks: A hissing sound usually indicates a leak. Check the connections between the muffler and the mid-pipe, and the connections to the header (if applicable). Tighten the clamps or bolts in the leaking area. Ensure the surfaces are clean and free of debris.
Difficulty Removing the Stock Exhaust: Penetrating oil can be your best friend here. Let it soak for a while. Gently wiggle the muffler while pulling. Avoid using excessive force, as you could damage the mid-pipe.
Exhaust Doesn’t Fit Properly: Double-check that you have the correct exhaust for your Ninja 250R model year. Make sure all the mounting hardware is being used correctly. If you’re still having trouble, contact Two Brothers Racing or your local motorcycle mechanic.
Performance Issues: While a slip-on exhaust can improve performance, it’s usually a minor change. If you experience a significant decrease in performance, there might be a problem with the installation or the bike’s tuning. Consult a mechanic if necessary.
Excessive Vibration: Make sure all bolts and clamps are properly tightened. Check the exhaust for any contact with the frame or other components.

Maintaining Your New Exhaust

To keep your Two Brothers Racing exhaust looking and performing its best, follow these maintenance tips: (See Also: Did Seve Ballesteros 1983 Slip On Masters Jacket )

Regular Cleaning: Clean the exhaust regularly with a mild soap and water solution. Avoid abrasive cleaners that could damage the finish.
Inspect for Damage: Periodically inspect the exhaust for any signs of damage, such as dents, cracks, or corrosion.
Check for Leaks: Listen for exhaust leaks and address them promptly.
Tighten Bolts: Check the tightness of the bolts and clamps periodically, especially after riding on rough roads.
Consider a Heat Shield: If you ride in an area with high heat, consider adding a heat shield to protect your fairings and other components from the exhaust’s heat.

Safety First: Important Reminders

Safety should always be your top priority. Remember these key safety points:

Wear Safety Gear: Always wear safety glasses, gloves, and appropriate clothing.
Work in a Well-Ventilated Area: Exhaust fumes can be dangerous.
Let the Bike Cool Down: Never work on a hot exhaust.
Use the Correct Tools: Using the right tools makes the job easier and safer.
Follow Torque Specifications: Over-tightening or under-tightening bolts can cause problems.
If in Doubt, Consult a Professional: If you’re not comfortable with any part of the installation, consult a qualified motorcycle mechanic.

Beyond the Basics: Further Enhancements

Now that you’ve upgraded your exhaust, you might consider other performance enhancements for your Ninja 250R. Keep in mind that these modifications might require additional tuning or adjustments.

Air Filter Upgrade: A high-flow air filter can help improve airflow.
Jet Kit or Fuel Management System: If you’ve significantly changed the exhaust or air intake, you might need to adjust the fuel delivery.
Suspension Upgrades: Improved suspension can enhance handling.
Tires: High-performance tires can provide better grip.
