Before You Begin

  • Ensure your motorcycle has had sufficient time to fully cool down before touching any exhaust components.
  • Check components against included packing list.
  • Wear gloves and other essential PPE.
  • Ensure you have a basic set of tools, including a socket set and hex keys. A saw may be required if the original exhaust requires cutting to be removed.

Removing the O.E Exhaust

  • Spray all bolts and joints with lubricant and allow time to penetrate.
  • If your motorcycle has an exhaust valve, this will need to be disconnected. Detailed instructions for this will be included within the product documentation.
  • NOTE: Some O.E exhausts are installed as one piece, and may need to be cut before they can be removed. Detailed instructions will be included if point is required.
  • Disconnect Lambda cable or unbolt from pipework if applicable.
  • NOTE: On certain motorcycles, it may be necessary to remove components to gain access to clamps/fixings etc.
  • Remove the original exhaust system starting from the back of the motorcycle and working to the front.
  • Original exhaust systems can be heavy due to the materials they are made from, and the size of silencers. Take care when removing the exhaust to avoid any damage to your motorcycle.

Fitting The Scorpion System

  • If a bracket is supplied, fit this to the bike as shown on the included fitting diagram.
  • Offer the silencer up to your motorcycle, with any exhaust clamps loosely slipped over the pipe work.
  • Ensure OE gaskets have been removed if stated.
  • Begin to install the Scorpion system, working from the front to the rear of your motorcycle.
  • We recommend smearing a small amount of high-temperature silicon inside each slotted/slip joint. This will help prevent any leaks and prevent pipework from seizing together.
  • Loosely tighten the clamps and brackets as you are fitting the system.

Final Checks

  • Ensure system is lined up correctly, and fit spring clamps if required.
  • Tighten the clamps from the front to the rear of your motorcycle. Make any required adjustments as you are going along, and be careful to not overtighten clamps.
  • If heat shields are provided, fit these now.
  • Ensure the exhaust is clear of any moving parts.
  • Wipe any oil/grease from the Scorpion system.
  • Start your motorcycle up in a well ventilated area and leave to tick over for around 10 - 15 minutes.
  • Check the system for any leaks.
  • Take your motorcycle for a test ride, and drive at various engine speeds to allow the exhaust to settle in properly.
  • Allow the exhaust to partially cool down, and then re-check that all joints are adequately tightened and ensure there are sufficient clearances around the exhaust system.


Exhaust components will be hot after test riding. Use gloves and take extra care.
