Welcome into the category dedicated to Roadsitalia sport exhausts for Ducati ST2 ST3 ST4 ST4S.
Within this category are shown all models of Roadsitalia exhausts that can be installed on the Ducati ST2 ST3 ST4 ST4S.
By installing a Roadsitalia sports exhaust, significant benefits are obtained, including: the sound becomes sportier, the look of the bike is clearly improved, engine performance is increased, the weight of the bike is reduced (making it more agile and lighter), and heat from the original exhaust system is reduced thanks to the greater speed at which exhaust gases flow outwards.
All models are approved for use on public roads throughout Europe and Switzerland (the certificate is included) and the silencers are equipped with a db-killer. Customers who want a less sporty sound can opt for the No-Noise version of the Db Killer (optional), which uses an internal metal mesh to further reduce the sound.
If it is possible to add a catalyzer as an option, we recommend that you purchase it so that you receive dual homologation for road use (sound and exhaust emissions). An exhaust without a catalytic converter is only approved with regard to sound. If this option is not included in the product page, it means that you do not need to purchase it (you keep the original one or your motorbike is pre-2003).
It is not mandatory to remap the ECU or install an add-on module. The Roadsitalia exhaust can be installed and used without the need for this type of modification. The more demanding customers who want to optimize the power and torque of the engine can evaluate this type of operation.
All models are supplied complete with fitting kit and can be installed without any modifications: the original exhaust is removed and the new Roadsitalia exhaust is installed.
To make it easier to choose the ideal model for your bike, we confirm that the difference between the various models is purely aesthetic, so choose the one you prefer based on design and budget.
