Trumpets and Ram Pipes for Carburettors

Known the world over under various names such as Velocity Stacks, Air Horns, Trumpets or Ram Pipes, they allow you to "tune" your engine in a relatively simple way and on this page you will find our current offerings.

We will, in general, refer to them as "Trumpets".

Without going into the scientific aspects of the how & why of these trumpets, we'll try to make life as easy as possible for you and not only list everything that we can supply but also categorizing them.

This requires a short explanation.
There are four main categories: "Bolt-On", "Slot-In", "Full Radius" and "Motorcycle".

The latter, Motorcycle, is more or less self-explanatory and these trumpets have special ways of being attached to the carburettor, usually "clamped-on" or "screw-on".
This will be explained in the descriptions of the individual articles and of course clearly visible in the photographs.

Then we move on to "non-motorcycle":
There we basically have 2 types, thanks to Weber...
Most carburettors require bolt-on trumpets which are secured with 2 nuts and bolts (or studs).
Some older Weber DCOE carburettors sometimes use "slot-in" trumpets which are also used to keep the chokes (or venturis) in place.

Slot-in trumpets use special tabs to be secured to the carburettor.
You can find these tabs HERE.

If you don't have Weber DCOE's, then don't bother about the slot-in trumpets.
If you dó have DCOE's, then please check if Slot-In is the trumpet for you or that you can make do with bolt-ons.
Feeling unsure? Then please feel free to contact us with some photographs and we'll gladly advise you.

Then finally there is the base diameter of your carburetor that determines which diameter trumpet you need. Usually this is either 40 mm (the bulk of all twin carburettors) or 45 / 48 mm.
This size refers to the diameter of the throttle valve so in case of doubt, simply measure that valve (or disc) to find out what you have although most makes have that size cast into some part of the carburetor.
Oddly enough, 45 and 48 mm carburettors are often drilled the same diameter at the air inlet side so in many cases (not all!) trumpets for 45 mm carburettors will also fit the 48 mm version.
A decent quality caliper will be a great help in this case.

The Full Radius section is for trumpets with a "full radius edge". Being more difficult to manufacture, and therewith more expensive, their design offers distinct advantages in terms of the "fluid dynamics" of the air that is being sucked into the engine.
