Yamaha LeoVince

Sito, then LeoVince

The company itself is older than the brand name on the box. It started in 1954 in Turin, building replacement two-stroke and four-stroke silencers under the Sito name — work still sold today. LeoVince as its own brand followed later, launched in 1987 after LeoVince had already built a leading position in Europe for two-stroke scooter expansion chambers, and the four-stroke sportbike range that fills most of this shelf came along in 1999. The current owner, Belgrove Sp. z o.o., took over every LeoVince brand together with the whole R&D department and manufacturing organisation in February 2014, and restarted production and distribution from there. Design, testing and homologation are all done in-house at LeoVince's own facility in Monticello d'Alba, Italy, rather than farmed out.

What their own history page does not do is put a number on any of it. It talks about being "alongside the best teams and riders" in MotoGP, Superbike, Motocross and Enduro since 1954 — no title count, no name, no year attached to any of it. That is a thinner claim than a racing pedigree usually gets written up as, and it is worth reporting plainly rather than reading more into it than LeoVince themselves do.

Which line is which

LeoVince sell under one name but several distinct lines, and it is the line — not the marque — that tells you what kind of product a listing actually is. Stainless steel is what most of what we stock is built from; titanium and carbon fibre make up a smaller, lighter premium share. Most lines mix slip-on mufflers and full systems under the same name, so treat the table below as the family, not a guarantee of which type a specific listing is — that is always worth checking on the listing itself.

The E-PASS certificate, and what it isn't

For a road-going exhaust, the document that actually matters is what LeoVince call the E-PASS certificate, included in the printed user manual that ships with the part. LeoVince say plainly that a separate "homologation card" some listings also mention does not replace it — two different pieces of paper, easy to confuse for one another. The approval itself is scoped to a specific vehicle "Type" named on the certificate, not to every bike sold under a given model name, so it is the Type on your documents that has to match, not just the model.

LeoVince mark each product's status themselves, on their own product pages: an "ECE-Approved" badge with a downloadable certificate where a fitment qualifies, or "Not approved" / "Not for road use" where it does not. That marking, against the exact part number, is what to check before you order — or ask the parts desk to check it for you. It is also worth knowing that LeoVince's own position is that meeting the required noise limits does not strictly need a DB Killer at all; where one is fitted on an approved system, they require it to be fixed rather than removable, and say that taking out a welded one ends both the road approval and the product warranty at the same time.

Two products, one word apart

This shelf also stocks the smaller parts that go with a system rather than replace the whole thing: DB Killer inserts on their own, heat shields, footpeg removal kits, exhaust clamps, gaskets, an O2 Extension Wire, and both 4-Stroke Header Pipes and Mid Pipes for a partial rebuild rather than a full system swap. Two of those spares are worth reading carefully before you order, because they do opposite jobs on overlapping fitments.

The two names are one word apart and the parts do opposite things. Check exactly which one is in the listing before you order, and ask the parts desk if you are not sure which your bike and your use of it actually needs.

What owners say about fitting one

LeoVince host their own product reviews, dated and country-flagged, directly on the product pages — a fuller picture than our own site can offer, since customer reviews are not something our own listings really carry yet. Across the fitments we checked, installation is repeatedly described as quick and straightforward, including by reviewers who said they had never fitted an exhaust before. Sound is not unanimous, which is worth knowing before you assume aftermarket always means louder: alongside reviewers pleased with the change, at least two independently described the result as quieter than they expected. One buyer, reviewing a fitment bought through a different retailer, reported that a slip-on fit the bike correctly but would not clear the factory panniers without custom welding — a single report rather than a pattern, but worth checking before you order if your bike runs panniers.

This shelf carries the finished systems and mufflers; the DB Killer inserts, clamps, gaskets and other spares that keep one running are on the exhaust parts and accessories page instead. Whichever LeoVince line is right for your bike, it is for sale at 10% off RRP with free UK delivery available — and if what you are still deciding is slip-on against full system rather than which brand, that choice is covered on the wider exhausts page.
