Important Preparation Tips Before Installing Your Hitchcox Motorcycles Slip-On Exhaust
- Allow the motorcycle to cool completely before beginning work

- Apply a light amount of anti-seize to all exhaust joints and bolts during assembly
- Avoid touching brushed or ceramic-coated surfaces with oily hands

Step-by-Step: How to Fit the Hitchcox Motorcycles Street Scrambler Shotgun Slip-On Exhaust
Step 1: Remove the OEM Heat Shields
Carefully remove the factory heat shields using the appropriate Allen key or socket. Place all hardware safely to one side, as the original heat shields will be reused with your Hitchcox Motorcycles slip-on exhaust.
Handy Tip: Wrap removed parts in a cloth to avoid scratching painted or ceramic surfaces.
Step 2: Loosen the OEM Exhaust Mounting Bolts
Locate the mounting bolts securing the stock silencers to the motorcycle frame.
- Loosen the mounting hardware first
- Then loosen the clamp/joint connecting the silencers to the catalytic converter
- Do not fully tighten or remove hardware until all components are free-moving
Step 3: Remove the OEM Silencers
Carefully slide the stock silencers rearward from the catalytic converter outlets.
If the pipes feel tight:
- Use a gentle twisting motion
- Apply penetrating oil if necessary
- Avoid excessive force
Handy Tip: A rubber mallet can help loosen stubborn exhaust joints without damaging surfaces.
Step 4: Prepare Your Hitchcox Motorcycles Shotgun Slip-On Exhaust
Unpack the new shotgun slip-ons and inspect:
- Mounting brackets
- Clamps
- dB killers (if fitted)
- Fasteners
Apply a thin layer of anti-seize to all slip joints and bolt threads. This helps prevent future seizure from heat cycles, an important step with any quality aftermarket exhaust.
Step 5: Fit the Hitchcox Triumph Street Scrambler Slip-On Exhaust
Slide each shotgun slip-on onto the OEM catalytic converter outlets and loosely install the exhaust clamps and mounting bolts. Do not fully tighten yet.
Ensure:
- Both silencers sit evenly
- Adequate clearance exists around the swingarm, shocks, and bodywork
- The outlet alignment is symmetrical
Step 6: Refit the OEM Heat Shields
Reinstall the factory heat shields onto the original mounting points. The Hitchcox Motorcycles aftermarket exhaust design allows the stock shields to bolt back into place for both appearance and rider protection.
Handy Tip: Check that the heat shields do not contact the silencers directly to avoid vibration marks.
Step 7: Final Alignment and Tightening
Once satisfied with the fitment:
- Tighten the exhaust mounting bolts
- Tighten the exhaust clamps
- Double-check all fasteners
Use a torque wrench where possible and tighten evenly.
Important: Do not overtighten exhaust clamps, especially on ceramic-coated Hitchcox Motorcycles exhaust systems.
Step 8: First Start-Up Check After Fitting Your Aftermarket Exhaust
Start the motorcycle and allow it to idle. Check for:
- Exhaust leaks
- Rattles
- Vibration
- Clearance issues
A small amount of smoke or smell from oils burning off during the first heat cycle is completely normal with any new aftermarket exhaust fitment.
dB Killer Information - Hitchcox Street Scrambler Slip-On Exhaust
If your Hitchcox Motorcycles exhaust system includes removable dB killers:
- They are secured with M5 bolts within the exhaust outlet
- Ensure they are tightened securely before riding

After Installation: Post-Fit Checks for Your Triumph Exhaust
After the first 50–100 miles:
- Recheck all mounting bolts and clamps
- Inspect for movement after heat cycling
- Clean the exhaust with a microfibre cloth once cooled
