Allow the exhaust to cool: Before starting, let the exhaust cool completely to avoid burns. Ideally, work on a cold engine.
Secure the motorcycle: Use wheel chocks and a jack or lift to ensure stability.
Disconnect the battery (optional but recommended): This prevents accidental electrical shorts. Disconnect the negative (black) terminal first, then the positive (red) terminal. Reconnect in reverse order.
Follow torque specifications: Over-tightening can damage threads; under-tightening can lead to leaks and vibration.
Be mindful of hot surfaces: The engine and exhaust components can retain heat long after the engine is turned off.

Step-by-Step Installation Guide

Now, let’s get into the step-by-step process of installing your new slip-on exhausts. Remember to consult your owner’s manual for any specific instructions related to your Tri Glide model.

Step 1: Preparation and Motorcycle Support

Prepare the Motorcycle: Park your Tri Glide on a level surface. Engage the parking brake.
Secure the Front Wheel: Place wheel chocks in front of the front wheel to prevent rolling.
Lift or Jack the Motorcycle: If you have a motorcycle lift, use it to raise the rear of the bike, providing easier access to the exhaust. If using a jack, place it under the frame, ensuring proper support. Alternatively, you can work on the ground, but access may be more limited. Make sure the bike is stable.
Locate the Exhaust Components: Familiarize yourself with the stock exhaust system. Identify the slip-on mufflers, the mounting hardware, and any associated brackets.

Step 2: Removing the Old Exhaust

Loosen the Exhaust Clamps: Locate the clamps that secure the slip-on mufflers to the exhaust header pipes. These are usually near the front of the mufflers. Use a socket or wrench to loosen the clamps. You might need penetrating oil if they are corroded.
Remove the Mufflers: Carefully slide the old mufflers off the header pipes. They might be stuck, so gently wiggle and twist them while pulling. Use WD-40 or a similar lubricant to help loosen them if needed. Be careful not to damage the header pipes.
Remove Mounting Hardware: Remove any brackets or hardware that secure the mufflers to the frame. Keep track of all the bolts, nuts, and washers.
Inspect the Exhaust Gaskets (If Applicable): Check if your new exhaust requires new gaskets. If so, remove the old gaskets from the exhaust ports on the engine. If the new exhaust includes gaskets, install them now.
Clean the Header Pipes: Use a wire brush or scraper to remove any carbon buildup or debris from the header pipes where the new mufflers will connect. This ensures a good seal.

Step 3: Installing the New Slip-on Exhausts

Prepare the New Exhausts: Inspect the new slip-on exhausts for any pre-installed hardware. Ensure all necessary components are present.
Install the New Mufflers: Carefully slide the new mufflers onto the header pipes. Make sure they are fully seated.
Secure the Clamps: Position the exhaust clamps over the connections between the mufflers and the header pipes. Tighten the clamps, but do not fully tighten them yet. Leave them slightly loose so you can adjust the position of the mufflers.
Attach Mounting Hardware: Install any brackets or hardware that secure the mufflers to the frame.
Align and Adjust: Ensure the mufflers are properly aligned and that they do not interfere with any other components on the motorcycle. Make any necessary adjustments.
Tighten the Clamps: Once you are satisfied with the alignment, tighten the exhaust clamps to the manufacturer’s specified torque. Use a torque wrench for accuracy.
Tighten Mounting Hardware: Tighten all mounting hardware to the manufacturer’s specified torque.
Double-Check: Inspect all connections and hardware to ensure everything is secure.

Step 4: Final Steps and Testing

Reconnect the Battery (If Disconnected): If you disconnected the battery, reconnect the positive (red) terminal first, then the negative (black) terminal.
Start the Engine: Start the engine and let it run for a few minutes.
Check for Leaks: Listen for any exhaust leaks. You might hear a hissing sound if there are any leaks. You can also feel for leaks by placing your hand near the connections (be careful of the heat!).
Test Ride (After Cool Down): Once the engine has cooled down, take your Tri Glide for a short test ride. Listen for any unusual noises or vibrations.
Re-torque if Necessary: After the test ride, let the exhaust cool completely and re-torque the clamps and mounting hardware.
