Step 2: Locate and Identify the Stock Exhaust Components
Identify the stock muffler and the connection points. These typically include the exhaust clamp(s) that secure the muffler to the mid-pipe or header pipes, and any mounting brackets that secure the muffler to the frame of the motorcycle. Take note of the position of any O2 sensors or other components that may be connected to the exhaust. (See Also: Won Hundred Willow Slip On Sneakers )
Step 3: Loosen and Remove the Stock Exhaust
Start by loosening the exhaust clamp(s) connecting the muffler to the mid-pipe or header pipes. Penetrating oil can be helpful if the bolts are corroded. Use the appropriate-sized wrench or socket to loosen the clamp bolts. Once the clamps are loose, carefully detach the muffler from the mid-pipe/header. Then, remove any mounting bolts or brackets that secure the muffler to the frame. Gently wiggle and pull the stock muffler to remove it from the bike. Be careful not to damage any other components during this process.
If the muffler is stuck, try the following:
- Penetrating Oil: Apply penetrating oil to the connection points and let it sit for a while.
- Gentle Tapping: Use a rubber mallet to gently tap the muffler to help loosen it.
- Heat: (Use with caution) Applying heat from a heat gun or torch can help expand the metal and loosen the connection.
Step 4: Prepare the New Slip-on Exhaust
Unpack your new slip-on exhaust and familiarize yourself with its components. Check the package to ensure all parts are included. Locate any mounting hardware, such as brackets, clamps, and bolts, that came with the new exhaust. Inspect the slip-on for any pre-installed components, like the exhaust flange or mounting brackets.
Step 5: Install the New Slip-on Exhaust
Carefully slide the new slip-on muffler onto the mid-pipe or header pipes. Align the muffler with the mounting points on the frame. Install the exhaust clamp(s) and mounting hardware. Ensure the muffler is correctly positioned and aligned with the bike’s bodywork. Do not fully tighten the clamps or mounting bolts at this stage; leave them slightly loose so you can make adjustments.
Important note: Some slip-on exhausts may require the use of the stock exhaust gasket or a new one provided with the slip-on. Ensure the gasket is properly seated to prevent exhaust leaks.
Step 6: Tighten the Clamps and Mounting Hardware
Once you are satisfied with the alignment of the new exhaust, begin tightening the exhaust clamp(s) and mounting bolts. Use a torque wrench to tighten the bolts to the manufacturer’s specified torque, which can be found in your owner’s manual or the slip-on exhaust’s instructions. Start with the mounting bolts to secure the muffler to the frame. Then, tighten the exhaust clamp(s) that connect the muffler to the mid-pipe or header pipes. Ensure the clamp is evenly tightened around the connection to provide a secure seal. Do not overtighten the bolts, as this can damage the exhaust system.
