Exhausts Ducati Monster 600 620 695 750 800 900 1000 S4

The air-cooled desmodromic V-twin - in its long evolution from the 600 to the 1000, through the 750, 800, 900 and the S4 versions - remains one of the most recognisable engines in motorcycling history. The Monster family built around this powertrain spanned over a decade of production, from 1993 to the mid-2000s, and each displacement carries its own distinctive sound character. It is precisely the tone of the Ducati L-twin that makes these models so well suited to a targeted upgrade on the exhaust end: the base sound is already there, it just needs to be released with a component that works better than the original. If you are looking for exhausts for Ducati, here you will find our range dedicated to the classic Monster family, with model-specific dual side-mount silencers for every version.

What we offer for this platform is a kit consisting of two silencers - right and left - designed to replace the original end cans. This is not a full exhaust system: the original headers remain in place, and the kit connects directly to the standard mounting points with no modifications required to the frame or the existing exhaust layout. Everything needed for installation is included in the package. We always recommend relying on a mechanic experienced with Ducati motorcycles for a proper fitment, especially for bracket adjustment and correct clamp tightening.

We offer two mounting configurations: a classic low side-mount version, with the two silencers positioned traditionally on both sides, and a high side-mount version near the tail, still with dual right and left exhaust but with a more tucked-in, sportier positioning. The choice between the two is mainly aesthetic, but it can also affect weight distribution and clearance during city riding or low-speed manoeuvres.

In terms of real-world benefits, replacing the original end cans delivers a noticeable weight reduction - the stock silencers on these Monsters are quite heavy - and a perceptible change in exhaust tone. The sound becomes more open and defined, with that deep note typical of the Ducati V-twin becoming more prominent, especially on acceleration and downshifts. We are not talking about radical performance gains: the silencer works on the final section of the exhaust system, and the benefits are mainly acoustic and aesthetic, along with a contribution to the overall weight saving of the motorcycle.

Since this family covers a very broad production span, the catalytic converter question deserves attention. The Monster 600, 750 and 900 produced up to 2001-2002, as well as the early S4 models, were homologated under Euro 0 or Euro 1 and did not feature a catalytic converter as standard: on these models it is entirely appropriate to fit a silencer without a catalytic converter, because the motorcycle did not have one originally. The Monster 695, produced from 2006 to 2008, falls under Euro 3 regulations and comes with a catalytic converter from the factory: for this version, choosing the catalysed variant is the correct approach to maintain road-legal compliance. For the intermediate models - Monster 620, 800 and 1000 produced between 2002 and 2005 - the situation varies: some units have a catalytic converter, others do not, depending on the exact year and the Euro homologation shown on the registration document. When in doubt, the reference is always your vehicle's registration certificate. In the drop-down menu on the product page, you can select the version with or without catalytic converter based on your specific configuration.

Every exhaust is handcrafted in Lombardy, in the province of Bergamo, and made to order: each piece is built, inspected and shipped only after passing a careful quality check. This means delivery times are not those of an off-the-shelf product, but those of a custom-made item. Updated lead times are always visible at checkout, and upon dispatch you will automatically receive a tracking code to follow your shipment. Sold directly, with no middlemen, these exhausts come with support from people who know them inside out, both during the selection process and in after-sales support.

Each silencer comes with a standard dB killer fitted as standard. Its removal is not officially intended and would void the noise homologation. For those seeking an even quieter sound level - for example for predominantly urban use or to comply with particularly strict local regulations - the No-Noise option is available: a welded internal baffle that further reduces decibel levels without significantly penalising gas flow. This option is also selectable directly on the product page.

Since only the end cans are being replaced, the motorcycle's ECU does not normally require any remapping. The fuelling system adapts to the new component without generating faults, and no modifications to the engine management are needed. This applies particularly to the older models in the range, which use simpler injection systems or, in the case of the very first Monster 600 and 900 units, still run on carburettors.

For any questions about compatibility with your specific model, about the differences between the high and low mount versions, or about choosing between the configuration with or without catalytic converter, you can check the FAQ section on the website or contact us directly via the Contact page or the live chat. We respond quickly, and whoever answers knows these exhausts thoroughly.

To optimise the ECU as well, our Alientech Powergate 4 remapping kit is available, with up to 4 maps included, calibrated on the bike configuration: Ducati Monster raffreddato ad aria (2000-2015) and Ducati Monster S4 (2001-2003). The kit is compatible only with fuel-injected versions. The map also removes the MIL warning light, which can come on with the non-catalysed version.

Below you will find the product list available for the Ducati Monster 600, 620, 695, 750, 800, 900, 1000 and S4 family. The differences between the various options are mainly aesthetic: body shape, construction material and type of finish. On each product page you can select the variant with or without catalytic converter, and the No-Noise option from the drop-down menu.
