Planning a motorcycle exhaust upgrade? Choosing the system is only part of the job. Before ordering, check how it fits your exact bike, what installation components are required and whether the manufacturer specifies any ECU tuning or setup changes.
This guide explains the questions to ask. It is not a replacement for the instructions supplied with your exhaust or tuning equipment, or for advice from a qualified motorcycle technician.
Start with your exact motorcycle specification
Confirm the make, full model name, model year and variant. Registration year alone may not identify the correct application. Tell us about existing exhaust, intake or ECU modifications and whether the motorcycle differs from the standard UK specification.
Use our Shop by Bike page to begin browsing, and read our motorcycle parts fitment guide if you are unsure which version you own.
Slip-on silencer or full exhaust system?
Slip-on silencers
A slip-on replaces part of the original exhaust, typically the silencer section. The exact arrangement varies by motorcycle and product. Check which original components remain, whether a dedicated link pipe is included and whether additional brackets or fittings are needed.
Full exhaust systems
A full system replaces more of the exhaust assembly, typically including the headers and silencer. Check the product's component list rather than assuming every fitting item is supplied. Installation and setup requirements can differ substantially from those of a slip-on.
Individual exhaust components
Headers, link pipes, silencers and fitting kits may be intended for a specific combination of parts. A component listed for your motorcycle is not automatically compatible with every aftermarket exhaust for that bike.
Does a new exhaust need ECU tuning?
There is no single answer for every motorcycle and exhaust. Do not assume that every slip-on needs a remap, or that every system can be used without one.
The correct approach depends on the exact motorcycle, exhaust configuration, intake setup and the manufacturer's instructions. Before buying, establish:
- Whether the exhaust manufacturer specifies a matching ECU calibration or other setup work.
- Whether the proposed calibration supports your exact model year and ECU.
- Which exhaust and intake configuration the calibration is designed for.
- Whether any previous ECU changes must be identified before installation.
- Who will carry out the fitting, checks and any required calibration.
If the requirements are unclear, pause and ask before ordering or running the motorcycle with the new configuration.
What does ECU tuning do?
The ECU manages engine operation. A tuning product or calibration changes selected control settings for a supported application. It is not a universal way to make any exhaust compatible with any motorcycle.
Compatibility and results depend on the bike, its condition, the installed hardware and the calibration used. Do not choose a tuning product solely because another rider has the same model name, and do not expect a guaranteed power increase from an exhaust or map.
Considering an UpMap tuning device?
Check the current manufacturer's compatibility information for the exact device, motorcycle and calibration before purchasing. Confirm any required connection cable, app requirements, map availability and what is included with the product.
Ask whether the calibration matches your specific exhaust and intake configuration. Do not assume that a device includes every map or that a map intended for one system is suitable for another. For pairing, installation, recovery and support procedures, follow the current instructions for that device.
Plan the installation before starting
- Read the instructions first. Check the required tools, fitting sequence, replacement consumables and any specialist procedures.
- Check the supplied components. Compare the contents with the manufacturer's parts list before dismantling the original exhaust.
- Use a suitable working environment. Work only with the motorcycle securely supported and the exhaust cool. If you cannot do this safely, arrange professional installation.
- Follow model-specific specifications. Use the manufacturer's tightening torques and procedures, not generic figures from another motorcycle.
- Check clearances and connections. Have the installer confirm the position of the system relative to bodywork, controls, luggage and other fitted equipment, and follow instructions for any sensors or wiring.
- Complete the specified setup and checks. Follow the exhaust and tuning manufacturers' instructions before riding.
Do not force components together, improvise mounting arrangements or continue installation when parts do not align as instructed.
Checks after installation
Have the installer check for leaks, secure mounting and suitable clearances, and complete any manufacturer-specified checks after the initial heat cycle. Follow any instructions for later inspection or fastener checks.
If the motorcycle develops warning lights, unusual running, excessive heat, leaks or unexpected noises, stop using it and seek qualified advice. Do not assume a new map will resolve a mechanical fitting problem.
Questions to send us before you order
