Spark Exhaust Konix Evo Slip-On Titanium Euro 5 Ducati Multistrada V4 / V4 S (2021-2026) GDU1605TOM

Ducati's own Multistrada V4 silencer is already light at 2.8 kg. Spark's Konix Evo answers with 1.7 kg, an all-titanium build down to the internal end cap, and a Euro 5 certificate.

Key Features

• Konix Evo slip-on silencer for the Ducati Multistrada V4 and V4 S, 2021 to 2026.
• Entirely titanium: outer case, perforated inner mesh and internal end cap.
• Carbon fibre outlet end cap.
• 1.7 kg against 2.8 kg standard.
• Euro 5 homologated, supplied with the certificate.
• db killer fitted and not removable.
• The original heat shield can be refitted to the Spark connecting tube.
• Spark part number GDU1605TOM, made by Spark in Mantova, Italy.

Titanium All the Way In

Plenty of silencers are described as titanium and mean the outer sleeve. The Konix Evo means the whole thing: the case, the perforated mesh that runs down the middle, and the internal end cap are titanium as well.

That is where the difference against the previous Konix comes from. Spark's own comparison is that the Evo is extremely light precisely because it is entirely titanium rather than titanium on the outside. The result on a Multistrada is 1.1 kg saved against a standard part that was not heavy to begin with.

Built for the V4 Granturismo

The brief Spark set itself for the V4 Granturismo engine was three things at once: maximise performance, give the bike a dark and aggressive voice, and stay inside the Euro 5 sound limits. Those pull against each other, which is why the silencer is a specific development for this engine rather than a generic can with an adapter.

The Heat Shield Detail

A small thing that matters on a bike carrying panniers and a passenger: the Multistrada's original heat shield can be installed on Spark's connecting tube. You do not lose the protection Ducati fitted, and the area around the pannier and the pillion's boot stays as it was.

The db Killer Is Not Removable

Spark states it plainly and we will too: the db killer on this slip-on is fitted and cannot be taken out. That is a deliberate consequence of the homologation — the certificate describes the silencer as it leaves the factory, and there is no configuration that would fall outside it.

If you were expecting a louder track setting from this article, it does not have one. What it has is a certificate that does not need explaining at a roadside check.

Racing Design, Road Paperwork

The Konix Evo is an aggressive shape — a tapered wedge with the carbon cap cut back at the outlet, closer to what Spark builds for the circuit than to what Ducati hangs on a touring bike. The certificate is what lets it stay on a bike that crosses borders.

What Stays on the Bike

This is a slip-on, so the Multistrada keeps its original collector and its catalyst. That is the reason the Euro 5 certificate exists at all, and it is also why the installation is measured in hours rather than in a day off work.

Nothing is cut and nothing is drilled. The standard silencer can go back on with its own fasteners whenever the bike is sold, which on a Multistrada is worth more than it sounds — these machines change hands with their service history and their original parts.

Fitment & Compatibility
