The Ducati XDiavel V4 comes with a stainless-steel exhaust muffler that ends in four visible exit pipes. Ducati also offers a full racing exhaust accessory, which it says adds 11 hp and removes 24.2 lb—but Ducati explicitly says the system is not homologated for road use. The performance figures are manufacturer claims, not independently verified test results.
What comes on the standard XDiavel V4?
Ducati describes the standard setup as a stainless-steel muffler with four exit pipes, designed as a prominent part of the bike’s appearance. The XDiavel V4’s 1,158 cc, 90-degree V4 Granturismo engine uses a Twin Pulse firing order; Ducati says that firing order contributes to the engine’s characteristic sound. That is the manufacturer’s description, not a measured sound comparison between exhaust configurations. Ducati XDiavel V4 US product page
Ducati lists the standard motorcycle at 168 hp (124 kW) at 10,750 rpm and 93 lb-ft (126 Nm) at 7,500 rpm. Ducati XDiavel V4 technical data
What does the optional racing exhaust change?
Ducati’s US product page states: “A full racing exhaust system, not homologated for road use, is available as an accessory, boosting power by 11 hp and shaving off 24.2 lb.” The figures describe Ducati’s claim for the optional full system; the page does not provide a test protocol or independent verification. The stated power gain is not a new published peak-power figure, so it should not be treated as a separately verified output for every bike or market.

The key practical distinction is use: Ducati says this racing system is not homologated for road use. Riders should not assume it is legal for public-road use; applicable local requirements may impose additional restrictions.
Standard and racing exhaust compared
| Configuration | Power information | Weight information | Use status | Price and availability |
|---|---|---|---|---|
| Standard exhaust | Ducati lists the motorcycle at 168 hp (124 kW) at 10,750 rpm. | Not stated on Ducati’s cited product page. | Standard exhaust configuration; a specific homologation statement for it is not given on the cited page. | The US XDiavel V4 page displayed a motorcycle starting price of $28,995 when accessed in 2026. No standard-exhaust-only price is stated. |
| Optional full racing exhaust | Ducati claims an 11 hp increase; no test protocol is supplied. | Ducati claims a 24.2 lb reduction; no test protocol is supplied. | Ducati says it is not homologated for road use. | Accessory price and merchant inventory were not stated on the cited Ducati page. |
These are not two independently tested output measurements: the standard bike’s peak rating and the racing system’s claimed gain come from different statements on Ducati’s page. The source does not establish the racing system’s resulting peak power under specified test conditions.

- 🏍️【Select the Correct Inlet】Motorcycle Exhaust Muffler for Ducati XDiavel 2016-2024, Available with a 51 mm or 60 mm inlet option. Measure the outside diameter of the motorcycle’s connecting or mid-pipe at the mounting point and choose the matching variation before ordering. Also confirm bracket position, installation angle, swingarm clearance, and distance from the tire and bodywork.
- 🛠️【Stainless Steel Construction】The muffler uses stainless steel for the inlet, outlet, and main structure, with a black carbon-fiber-patterned outer surface for a modified appearance. Welded joints, fasteners, and a metal mounting band support the cylindrical assembly. The angled outlet gives the motorcycle a compact, performance-inspired visual update without using brand-specific graphics.
- 📏【Compact Cylindrical Profile】The complete muffler measures approximately 310 mm (12.2 in) long, with a main body length of about 195 mm (7.7 in) and an angled outlet section approximately 140 mm (5.5 in) across. Its short cylindrical format is intended for custom exhaust layouts where the confirmed inlet diameter and available mounting space match.
- 🔧【Slip-On Modification Part】Slide the selected inlet over a compatible connecting pipe, align the outlet and mounting point, then secure every connection before starting the engine. Installation may require a model-specific mid-pipe, adapter, clamp, springs, bracket, gasket, tuning, or fabrication; these parts are not included unless separately listed. Professional installation is recommended.
- ⚠️【Check Rules and Fit Before Use】Exhaust changes may affect sound level, emissions compliance, engine operation, and road legality. Check local requirements before installation and do not treat this muffler as a catalytic converter replacement or certified emissions component. After mounting, inspect for leaks, loose fasteners, heat contact, tire clearance, and secure support before every ride.
What Ducati’s figures do—and don’t—establish
- Power: Ducati claims the accessory increases power by 11 hp, but publishes no test conditions or independent result alongside that claim.
- Weight: Ducati claims a 24.2 lb reduction. The page does not identify the comparison baseline or describe a weighing method.
- Sound: Ducati attributes the engine’s characteristic sound to its Twin Pulse firing order; there is no measured comparison of standard and racing exhaust sound.
- Fitment and buying details: The cited US page establishes that Ducati offers the accessory, but does not state its price, installation details, or retail inventory. Confirm market- and model-year-specific fitment with Ducati or an authorized dealer before purchase.
Price context
Ducati’s US product page displayed a starting price of $28,995 for the XDiavel V4 when accessed in 2026. That is a market-specific, time-sensitive motorcycle price, not the price of the racing exhaust; Ducati’s page does not state an accessory price.
Quick Recap
