Classic Vespa

The venturi hole is Ø 26mm and perfectly fits carburetors of this size. To adapt it to smaller carburetors, it is necessary to file the first part of the carburetor's intake duct. To adapt it to carburetors with a diameter greater than 26mm, it is necessary to slightly file the venturi to fit the carburetor's diameter.
Advantages:

Improves engine performance
Increases power, acceleration, and top speed
Compatibility with carburetors with or without a mixer
Possibility to mount an air filter directly in the box
Stylish and classic look
Non-deformable aluminum body

7-port aluminum cylinder with Nikasil-coated bore and exhaust "Booster".
Bore diameter 63mm, stroke 57mm, displacement 177cc,
main transfer phases 117°, exhaust 177°. Meteor dual-ring aluminum alloy piston

Die-cast aluminum head with 8 fixing points with recessed squish band
Steel rings. Steel pin. Steel retainers.
Cylinder gaskets in paper/aluminum.
Zinc-plated steel exhaust manifold bolted with Viton O-ring gasket.

Mounts on Et3 frames with the side compartment, on Pk frames it is necessary to slightly cut the bulkhead to allow the expansion curve to pass through.

On pre-1976 Primavera frames, the compartment is deeper and may limit the installation of the exhaust.

Designed to give the best performance on 125/185 timing, it adapts to a wider range of timings.

It fits very well with long-stroke 130cc cylinders that have a 32mm exhaust diameter.

VMC SILURO SPORT Exhaust for Vespa small frame

The exhaust has been designed and developed to be super performance while maintaining a classic and original look and sound.

It is entirely constructed from stamped steel sheets and assembled
by craftsmen welders with a decade of experience in making
2T exhausts.

The VMC SILURO "SPORT" version has a 32mm diameter exhaust flange and
slotted mounting holes that adapt to cylinders with a stud spacing of 52, 56, and 60mm.

It fits very well with performance cylinders such as the VMC GS series in
Cast Iron, the VMC ET6 and ET7 aluminum cylinders both 135cc and 144cc,
Pinasco Zuera, Quattrini M1 series (M1 56-60, M1-60B, M1L 56-60), the
EGIG 170cc cast iron cylinder, etc.

This exhaust enhances and unleashes the power and torque of the engine
right from low revs with an over-rev that can reach over 10,000 <
