DescriptionThe whole story▼
A silencer without a motorcycle attached to it. Spark's GP Style comes with the holder, the adapter tube and the db killer in the box, which makes it the most complete of the universal cans it builds.
Key Features
- Universal silencer in GP Style, AISI 304 stainless steel.

- Extra logo or marking possible on request.
- Not approved. This is a racing and custom part with no homologation certificate.
- Spark part number G00SI04I, made in Mantova, Italy.
What Universal Actually Means Here
It means the silencer is not built for one motorcycle, and it does not bolt onto one either. Spark supplies the can, a holder and a conic adapter tube; what joins that assembly to your header is a piece of pipework somebody has to cut, bend and weld.
That is why these articles live in the Custom Works part of Spark's range. They are the raw material for a one-off build, not a slip-on. If you were expecting a bolt-on replacement, look at Spark's bike-specific silencers instead and we will help you find the right number.
Both Sides, One Article
Spark lasers the logo into both flanks of the case, so there is no left-hand and no right-hand version of this silencer. Order one for a single-sided build or two for a twin, and the branding reads correctly whichever way it faces.
It sounds like a small thing. On a custom build where the exhaust is the visible line of the motorcycle, it decides whether a pair looks deliberate or improvised.
The Box Is the Point
Spark sells several universal silencers where the holder and the db killer are extras. This one includes all three parts: the case, the bracket that carries it, and the removable insert that brings the noise down.
For a builder pricing a project, that matters more than the sticker. A price with the hardware in it is a different number from the same price plus a holder plus an insert.
Made to Be Marked
Spark will add an extra logo or a custom marking on request. Shops that build under their own name use it; so do owners who want a plate number or a name on the case. Ask us before you order and we will put the request through with the article.
