Exhausts Ducati ST2 ST3 ST4 ST4S

The ST series stands as a chapter of its own in Ducati's history: a family of sport tourers born in 1997 with the ST2 and developed over the course of a decade through the ST3, ST4 and ST4S variants. Four models sharing the same tubular steel trellis frame and chassis layout — inverted forks, rear monoshock, Brembo brakes — yet profoundly different in their engine choices. The liquid-cooled 90° V-twin with desmodromic valve actuation is the common thread, but delivered in distinct architectures: two valves per cylinder on the ST2, four-valve Desmoquattro on the ST4 and ST4S (the latter powered by the 996-derived engine), and three-valve DesmoTre on the ST3. Motorcycles designed to cover serious distances without sacrificing riding pleasure, with a balance of comfort and sportiness that still makes them popular today among riders looking for a versatile Ducati. If you're looking for Ducati exhausts, this is the section dedicated to the ST family.

The silencers in this category are designed to replace the original end cans on your ST2, ST3, ST4 or ST4S. This is a pair of silencers in a dual configuration, with lateral fitment, connecting directly to the existing junctions on the stock system. The headers and mid-section of the exhaust remain original: the swap only involves the two end cans. Each pair comes with the necessary fitting kit for installation, compatible with the stock mounting points. Installation is within reach for those with motorcycle mechanical experience, but we still recommend having a qualified mechanic carry out the work to ensure correct fastening, joint sealing and proper alignment with the chassis.

Replacing the original end cans brings tangible benefits. The first is weight reduction: the stock silencers on the ST family are quite heavy, and shedding weight on both sides has a noticeable impact, especially during low-speed manoeuvres and on the bike's overall agility. The second is the exhaust note: Ducati's 90° V-twin has a distinctive voice, and an aftermarket silencer delivers a fuller, more defined sound with greater presence compared to the stock exhaust, without excess or uncontrolled noise. We don't promise power gains: the goal is to give the ST a sonic character more in tune with the engine's personality.

Every exhaust in this category is made through handcrafted manufacturing in Lombardy, at our facility in the province of Bergamo. We work to order: each pair of silencers is built, inspected and prepared for shipping individually. Quality control is carried out in-house before every dispatch, checking welds, finishes and fitment. We are the manufacturers and handle direct sales from the manufacturer: the relationship is between us and you, with no intermediaries.

For some models in the ST family, you can choose the sleeve length of the silencer, with options available between 280 mm and 400 mm. This selection is configurable directly from the drop-down menu within the product page, so you can tailor the look of the exhaust to your preferences or to the bike's setup, for example with or without side panniers.

Since only the end cans are being replaced, the rest of the original exhaust system remains in place. This means that ECU remapping is not normally required: the engine management system continues to operate on its original parameters without the need for any additional electronic modifications.

All our silencers come with a standard dB killer included. The dB killer is not officially removable: its removal invalidates the product's homologation. For those seeking even greater noise reduction, some products are available in a No-Noise version, fitted with a welded internal baffle that further reduces decibel levels without significantly affecting performance. This option is also selectable on the product page via the drop-down menu.

Up-to-date production lead times are always visible at checkout when placing your order. Once the product has been dispatched, you will automatically receive tracking information to follow your delivery.

For any questions about compatibility, configuration or installation, we invite you to consult the FAQ section of the website. If you need more specific support, you can reach us through the Contact page or use the chat: we reply directly and without excessive waiting times.

Below you will find the product list available for Ducati ST2, ST3, ST4 and ST4S. The differences between the various models are mainly aesthetic: silencer shape, material and finish. Within each product page you can select, where available, the No-Noise version and the sleeve length from the drop-down menu.
