When it comes to customising your bike, the exhaust system is often one of the elements that are considered first. Officine Italiane Zard knows this and that is why in its catalogue we find systems designed for many different motorbike models, often available in both racing and homologated versions. What are the differences between these two types and how do we choose the one that suits us?

What are the differences between a Racing and a Homologated exhaust?

Many of the exhaust systems produced by Officine Italiane Zard are available in both homologated and racing versions. Let's start by saying that, on an appearance level, the differences are minimal if not imperceptible: it is in fact inside the system that we find the differences between the two models. A homologated exhaust must in fact comply with the strict anti-pollution directives and will therefore be equipped with a more restrictive dB-killer, catalytic converter system and a greater quantity of sound-absorbing material, in order to fall within the air and noise emission limits set by law. The case is different for racing exhausts, which, not being subject to any restrictions, can be louder, with a more permissive dB-killer and less sound-absorbing material. They are also freer to 'breathe', as they have no catalytic converter.

What are the advantages of a racing exhaust?

Non-approved racing exhaust systems are designed for racing and track use and do not comply with noise and exhaust emission regulations. This means that they are not legal for use on public roads and can cause problems with local authorities if they are used in this way. In terms of performance, non-type-approved racing systems can offer a significant improvement over the OEM system due to their greater efficiency and the air flow optimised by the absence of a catalytic converter. In addition, they are lighter and offer better sound performance, with a more aggressive tone - but also many more decibels!

What are the advantages of a homologated exhaust?

A homologated Zard aftermarket exhaust system is the ideal solution for all motorcyclists who want to give their motorbike a distinctive character, thanks to the unique styling of Zard systems and the signature sound. In addition, the perfect execution of the materials used allows a net weight gain and an improvement in terms of power delivery. All these advantages, in the case of a homologated exhaust system, are combined with the certainty of using a product that is completely legal for use on public roads, and which does not risk the motorcyclist incurring sanctions or fines. 

Racing or homologated: How to choose your aftermarket exhaust system.

In summary, the choice between a non-homologated racing system and a homologated system depends on the personal preferences of the rider! If you want more power and an aggressive sound for track use or in a country where emission regulations do not apply, a non homologated racing system may be the best choice. If, on the other hand, you want improved performance and style but also want to comply with regulations, a homologated system for public road use is the most suitable choice. When ordering, please pay attention to the product description on zardlab.com: many exhausts are available in both versions, such as the complete exhaust system for the Harley-Davidson Sportster S 1250, while others are only available in the racing version or only in the homologated model, such as the products for the Triumph Speed Triple 1200!
