What You’ll Need
Before you begin, gather all the necessary items. Being prepared will make the installation process much smoother and more enjoyable. Here’s a comprehensive list:
- New Slip-On Exhausts: Make sure they are specifically designed for your Harley-Davidson Street Glide model and year.
- Tools:
- Socket set (metric and possibly SAE, depending on your bike’s year)
- Torque wrench (essential for proper bolt tightening)
- Wrench set (metric and possibly SAE)
- Screwdrivers (Phillips and flathead)
- Penetrating oil (like WD-40 or PB Blaster, in case bolts are stubborn)
- Gloves
- Safety glasses
- Jack and/or lift (optional, but makes the job easier)
- Wheel chocks
- Replacement Exhaust Gaskets: Highly recommended for a proper seal.
- Shop Towels: For cleaning and wiping.
- Anti-Seize Compound: To prevent future corrosion and make bolt removal easier.
- Torque Specifications: Consult your Harley-Davidson service manual for the correct torque values for each bolt. This is crucial to prevent damage.
Step-by-Step Installation Guide
Now, let’s get down to the actual installation. Follow these steps carefully.
Step 1: Preparation Is Key
Before you touch your bike, ensure it’s in a safe and stable position. Park it on a level surface, and use wheel chocks to prevent any movement. Let the engine cool down completely. Working on a hot exhaust system can lead to burns. Safety first! (See Also: Are Slip On Shoes Comfortable )
Step 2: Remove the Old Exhaust
This is where the real work begins. Start by:
- Locating the Exhaust Bolts: Identify the bolts that secure the stock slip-on mufflers to the head pipes. These are usually located near the exhaust ports on the cylinder heads.
- Loosening the Bolts: Apply penetrating oil to the bolts if they appear rusty or difficult to remove. Let it sit for a few minutes to work its magic. Then, using your wrench or socket set, carefully loosen the bolts. Be prepared for some resistance.
- Removing the Mufflers: Once the bolts are loose, carefully remove the stock mufflers. You might need to wiggle them a bit to break the seal. Be mindful of any clamps that might be holding them in place.
- Removing the Exhaust Gaskets: Old exhaust gaskets should be removed and new ones installed.
Step 3: Prepare the New Slip-on Exhausts
Before installing the new slip-ons, take a moment to inspect them. Ensure all the necessary hardware is included. Apply anti-seize compound to the threads of the bolts that will be used to secure the new mufflers. This will make future removal much easier.
Step 4: Install the New Slip-on Exhausts
Now comes the exciting part! Follow these steps:
- Position the New Mufflers: Carefully slide the new slip-on mufflers onto the head pipes. Ensure they are aligned correctly.
- Install the Hardware: Insert the bolts and hand-tighten them. Don’t fully tighten them yet, as you’ll need some play for adjustments.
- Adjust and Align: Make sure the mufflers are positioned as desired. Check for any interference with other parts of the bike.
- Tighten the Bolts: Using your torque wrench, tighten the bolts to the specifications listed in your Harley-Davidson service manual. This is crucial for a proper seal and to prevent leaks. Tighten the bolts in a crisscross pattern to ensure even pressure.
Step 5: Final Checks and Startup
Before starting your engine, perform a final inspection: (See Also: Was Bella Supposed To Slip On Ice In Twilight )
- Double-Check Bolts: Make sure all bolts are tightened to the correct torque.
- Inspect for Obstructions: Ensure the exhaust system isn’t interfering with any other parts of the bike.
- Wipe Clean: Clean any fingerprints or smudges from the exhaust.
Now, it’s time to start the engine. Listen for any exhaust leaks. If you hear any hissing sounds, it indicates a leak. You might need to re-tighten the bolts or check the gaskets. Let the engine run for a few minutes to allow the exhaust system to heat up. This will help to seat the gaskets and ensure a proper seal.
Tips for a Smooth Installation
Here are some extra tips to make the installation process even smoother:
- Take Your Time: Don’t rush the process. Rushing can lead to mistakes.
- Read the Instructions: Always read the instructions that come with your new slip-on exhausts. They might contain specific details for your model.
- Use the Right Tools: Using the correct tools will make the job much easier and reduce the risk of damaging your bike.
- Ask for Help: If you’re unsure about any step, don’t hesitate to ask for help from a friend, a local motorcycle shop, or online forums.
- Protect Your Bike: Use shop towels or other protective materials to prevent scratches on your bike’s paint.
- Torque Wrench is Essential: Do not skip the torque wrench. Over-tightening or under-tightening bolts can cause damage.
- Inspect the Head Pipes: While the mufflers are off, inspect the head pipes for any damage or leaks.
- Consider a Fuel Management System: While slip-on exhausts often don’t require it, a fuel management system (like a tuner) can optimize performance, especially if you’re making other modifications.
- Take Photos: Take photos during the disassembly process. This can be helpful if you get stuck during reassembly.
- Organize Your Hardware: Keep track of all the bolts and hardware. Use small containers or bags to keep them organized.
- Safety First, Always: Wear safety glasses and gloves throughout the process.
Common Problems and Troubleshooting
Even with careful planning, you might encounter a few problems. Here’s how to troubleshoot some common issues:
- Exhaust Leaks: If you hear hissing sounds, it indicates an exhaust leak. Check the following:
- Gaskets: Ensure the gaskets are properly seated and in good condition. Replace them if necessary.
- Bolts: Make sure the bolts are tightened to the correct torque.
- Alignment: Check the alignment of the mufflers and head pipes.
- Difficulty Removing Bolts: If the bolts are stuck, try the following:
- Penetrating Oil: Apply penetrating oil and let it sit for a while.
- Heat: Carefully apply heat to the bolt with a heat gun or torch (use caution).
- Impact Driver: Use an impact driver to help loosen the bolts.
- Muffler Interference: If the mufflers are interfering with other parts of the bike, try the following:
