DescriptionThe whole story▼
Three and a half newton metres at 3,100 rpm — barely above idle on a Testastretta twin, and the single most useful place to find torque on a naked bike ridden in town. The Akrapovic Slip-On Line (Titanium) S-D9SO17-HCQT gives the Ducati Monster 937 that, plus 2.2 PS higher up, and it won the Red Dot Award for Product Design in 2022 for how it looks doing it.
Key Features
- Two short mufflers that put the twin-cylinder layout on display instead of hiding it
- 3.5 Nm more torque at 3,100 rpm and 2.2 PS (1.6 kW) more power at 8,800 rpm against the standard system
- Outer sleeves and collector in lightweight titanium, sandblasted to an even matt finish; the remaining parts in high-grade stainless steel
- Red Dot Award for Product Design 2022, together with the matching carbon heat shield
- Euro 5 EC and ECE type approved, plug-and-play in about 30 minutes with no remapping
- Noise insert included for circuits with their own limit
- Fits the standard Monster 937 and the SP without modification
An Honest Word About Weight
This system weighs 3.07 kg. So does the standard one. Akrapovic's own measurement records no saving at all, and this listing is not going to pretend otherwise. The reasons to fit it are the torque low down, the sound, and the way two short titanium cans change the back of a Monster — not mass.
What the titanium does buy is finish and durability. The sleeves and the collector are sandblasted rather than polished, which on a bike parked outdoors ages far better than a mirror surface.
Design
The Red Dot jury awarded this exhaust together with the optional forged carbon fibre heat shield, which replaces the standard aluminium one. That heat shield is unusual: forged carbon is rare on a motorcycle part of this size, and it is genuinely optional — the standard aluminium shield can stay on with the Akrapovic silencer fitted.
Fitment and Compatibility
S-D9SO17-HCQT is developed for the Ducati Monster 937 and Monster 937 SP from model year 2021 through 2024. Two optional parts are available: the carbon fibre heat shield P-HSD9SO3 and a stainless steel link pipe, L-D9SO1, which raises power and torque and reduces weight. Fitting the optional link pipe makes the EC and ECE type approval of this silencer invalid.
Road Approval
EC type approval and ECE type approval to Euro 5, certificates supplied and downloadable here. As delivered, without the optional link pipe, the exhaust is a legal road part in the European Union.
