1. Can I fit the exhaust myself?

Pro-race exhausts are designed to be as easy as possible to install.

However please read the fitting instructions and safety notes carefully before attempting to fit the exhaust.

If you do not have the correct tools or have any doubts about your mechanical abilities, please contact us or have it fitted by a recognised bike dealer or a competent technician.

2. Can I use my exhaust on track-days?

Pro-race exhausts

(Depending on which design on which bike)

Combined with our removable baffles are designed to comply with current FIM/ACU (Superbike Regulations)

Generally, track days are run to these regulations and if your exhaust is correctly maintained you should have no problems.

All products will have the (DB Readings) Listed in the items description and will also come in the box with the installation instructions so you will be able to check certain track regulations beforehand.

Please Note:

All decibel readings are measured in the same method as most track days/race organisations on a completely standard bike with standard setup and mapping.

3. Will I need to re-jet / re-tune?

Please be aware: that your motorcycle is a production item and is subject to manufacturing tolerances, therefore no two bikes are identical.

The performance of your motorcycle is in effect a compromise to comply with various noise and emission laws in various countries.

However, making changes to your motorcycle exhaust will not suddenly cause it to not run, lose power or be damaged (Your bike will run correctly).

Generally, there are power gains due to our exhausts being less restrictive, and do not require re-mapping or re-jetting but to get the optimum performance we do recommend getting the bike set-up to the exhaust (but is not required)

4. Will it affect back pressure?

Talking about exhausts and very often you will hear the terms (Back Pressure) Or the (Right back pressure) comes up.

Back pressure is only caused by restriction and has little or nothing to do with performance exhaust design.

Although modern OE super bike exhaust systems are very well designed and can reduce noise levels to conform to emission laws without offering much actual back pressure these systems are to some degree still restrictive.

Performance exhausts work by (Pulse Tuning) which is the use of the correct pipe lengths, diameters and correct collector configurations to tune the exhausts pulses.

This will increase the efficiency, which will intern increase the power and torque.

5. Exhaust valves? will losing the valve lose me power?

Also known as Set Valves, Exup Valves etc…) To fit Pro-race exhausts on some models it is necessary to disconnect the exhaust valve. 

The primary function of this valve is noise control and not to boost power (if it was a power valve it would be on every race bike – it doesn’t appear on any!).  Therefore, disconnection of this valve will not result in a power loss or affect in any way the running of your motorcycle.

Please note: A warning light does appear on the dash when you disconnect the servo on some bikes, whilst the warning light does not damage your bike it can be easily fixed by installing a Servo Buddy or Heal tech servo eliminator plug.

On the models that require this the servo plug will be included in the exhaust kit / purchase 

See individual listings for each bike in the store tab for detailed information

6. How and when does my exhaust need repacking?

The nature of the product means that at intervals the exhausts will need to be repacked with sound absorption material. 

Pro-race exhaust systems only use Acoustafil branded premium packing. 

Service intervals will depend on how hard, how far and how often you ride your bike.  Regularly check the exhaust visually and listen for any changes in exhaust note.  

A service / Re-packing kit is available separately, or your exhaust can be returned to Pro-race and we will do it for you at a reasonable fee. 

Damage caused due to not repacking when needed may not be covered by warranty.

7. How do I clean my exhaust?


Clean the Exhaust with A Multi-Purpose Spray Lubricant

(WD-40 Or Equivalent) With A Soft Cloth.

Do Not Use Aggressive Chemical Cleaner


A change in the colour of the exhaust systems is normal due to the high temperatures.

8. I have had an accident with minor damage - can it be repaired?

This depends on the damage, but we will try our best to repair it,

Once the exhaust is returned to us we will assess and provide you a quotation of work required.

9. Can I buy spares?


Yes, all spare parts can be found in the accessories section in our store.

If you’re not able to identify the exact part, you require then please contact us 

10. Can I collect?

Yes, collections are welcome

but best to call first as 90% of our products are made to order due to the complexity of some products and the amount of exhausts we offer

it would be unrealistic to have them all sat on the shelf. But we will do our up most to get your exhaust built and ready for collection as fast as we can.
