  • Optional: Motorcycle stand or lift for easier access and stability during installation

Preparation

Proper preparation is key to a smooth installation. Follow these preparatory steps:

  • Ensure the motorcycle is completely cooled: Exhaust components can reach very high temperatures. Wait several hours after riding before starting.
  • Park on a stable, level surface: Use a motorcycle center stand or paddock stand to keep the bike upright and steady.
  • Read the manufacturer’s instructions: Akrapovic exhausts often come with model-specific guidelines and torque specifications that must be followed for best results.
  • Inspect all mounting points: Check for any damage or wear on the existing exhaust mounts and brackets that might need attention before installing the new system.
  • Gather all tools and lay out components: Organize parts and tools nearby to avoid searching during the process.

Removing the Stock Exhaust System

Carefully removing the stock exhaust is the first physical step in the upgrade. Follow these detailed instructions to avoid damaging your bike or the old components:

Step 1: Loosen Heat Shields and Accessories

Some Yamaha models have heat shields or additional covers attached to the exhaust. Use the appropriate screwdriver or Allen wrench to remove these parts. Keep all screws and small hardware organized.

Step 2: Loosen Exhaust Clamps and Mounting Bolts

Using the socket wrench or ratchet, begin loosening the bolts that secure the exhaust pipe to the manifold and the mounting brackets attached to the frame. These bolts can sometimes be corroded or tight, so apply penetrating oil and let it sit for a few minutes if necessary.

Step 3: Detach the Exhaust System Carefully

Once bolts are loosened, gently wiggle and pull the exhaust away from the manifold and mounts. Support the exhaust during this process to prevent it from falling and damaging the bike or itself. For some models, slight twisting may be required to free the exhaust.

Step 4: Inspect and Clean the Exhaust Ports

With the stock exhaust removed, inspect the exhaust ports on the cylinder head for any carbon buildup or debris. Use a clean rag or a soft brush to clean the surfaces. This ensures a proper seal when installing the new Akrapovic system.

Important Tips:

  • Label or photograph the location of bolts and brackets if you plan to reuse any hardware.
  • Do not force any parts; if a bolt is stuck, apply more lubricant and wait.
  • Keep the old exhaust system intact until the new one is fully installed in case you need to compare or revert.

Installing the Akrapovic Exhaust System

With the old exhaust removed, you are now ready to install the new Akrapovic system. Follow these steps carefully:

Step 1: Verify All Included Parts

Before installation, check that your Akrapovic exhaust kit contains all necessary components, including:

  • Muffler
  • Mid-pipe(s) or header pipes
  • Mounting brackets and clamps
  • Gaskets or sealing rings (if included)
  • Bolts and washers
  • Installation manual

Step 2: Install New Gaskets or Seals

If your Akrapovic kit includes new exhaust gaskets, replace the old ones at the manifold. These create an airtight seal to prevent leaks. Ensure they are seated properly.

Step 3: Attach Mid-Pipe or Header to Manifold

Carefully align the mid-pipe or header with the exhaust ports on the cylinder head. Slide it into place, ensuring the gasket remains aligned. Hand-tighten the flange bolts initially to hold the pipe in position.

Step 4: Position the Muffler and Connect Pipes

Attach the muffler to the mid-pipe or header as per your model’s design. This connection may use clamps or slip-fit joints. Secure them loosely at first to allow for adjustments.

Step 5: Attach Mounting Brackets and Clamps

Using the provided brackets and hardware, mount the exhaust system to the frame. Align the system so that it sits evenly without contact with the swingarm, footpegs, or other components. Hand-tighten all fasteners initially.

Step 6: Adjust and Tighten Bolts with Torque Wrench

Once everything is aligned correctly, use a torque wrench to tighten all bolts and clamps to the manufacturer’s specified torque settings. Proper torque ensures secure mounting and prevents damage from over-tightening.

Additional Installation Tips:

  • Use a silicone-based lubricant on the joints if needed to ease fitting.
  • Check clearance between the exhaust and bodywork to avoid heat damage.
  • Make sure the exhaust outlets are not obstructed or facing sensitive components.
  • If your model has a catalytic converter or an O2 sensor, install the new system according to Akrapovic’s instructions to maintain compliance and sensor functionality.

Post-Installation Checks and Break-In

After installation, perform the following checks and procedures to ensure optimal performance and longevity of your new exhaust system:

Step 1: Visual Inspection

Double-check all fasteners for tightness. Ensure clamps and brackets are firmly secured, and there are no visible gaps or misalignments.

Step 2: Start the Motorcycle

Start the engine and listen carefully for any unusual noises such as rattling, ticking, or exhaust leaks. A properly installed Akrapovic exhaust should produce a clean, deep sound without leaks or excessive drone.

Step 3: Check for Exhaust Leaks

Feel around the joints and connections for escaping gases. You can use a piece of tissue or your hand (careful of heat) to detect leaks. If leaks are detected, re-tighten clamps or bolts as needed.

Step 4: Test Ride

Take a short, cautious ride to verify that the bike runs smoothly and the exhaust is securely mounted. Pay attention to throttle response and overall engine behavior; some models may require ECU remapping or fuel controller adjustments to optimize performance with the new exhaust.
