SIP Performance Camaro Design racing muffler by NORDSPEED for Vespa 125 VNA-TS/150 VBA-Super/PX80-150/PE/Lusso

An ultra-high performance racing exhaust with a particularly broad and practical power delivery.

Where a four-stroke engine requires valves, a camshaft, an exhaust system, and a turbo, a two-stroke simply requires a well-designed exhaust system. A few pieces of sheet metal are molded to create a shape that perfectly matches the layout and size of the openings in the cylinder, known as transfer and exhaust ports. The design of the resonance chamber not only influences the removal of hot exhaust gases, but the pulse effect also influences the flow of fresh fuel mixture into the cylinder. On modern two-strokes, this technology is the main reason for their superiority over four-stroke engines.

As simple as the description may seem, creating a properly formed expansion chamber body is a science in itself. This is where the wheat is separated from the chaff. Truly good exhaust manufacturers are as rare as raw steak and often only produce limited runs, making their products typically expensive.

NORDSPEED, based in Bremen in northern Germany, enjoys an almost legendary reputation for producing excellent racing exhausts for vintage Vespa and Lambretta scooters.

SIP and NORDSPEED have joined forces in this field and the result is exhaust systems with the most powerful design, combined with modern features such as EGT and the possibility of connecting a lambda sensor.

Technical specifications of all SORD NORDSPEED exhaust systems:

- O-ring flange, suitable for all common cylinders.

- EGT connector.

- Lambda sensor connector.

- The flanged plate allows the attachment of the most common silencers.

Camaro:

The Camaro produces good torque and impresses with a noticeable powerband coupled with harmonious delivery. It can also deliver excellent top-end performance. Whether in an urban environment, commuting, or even touring through the mountains, the predictable power characteristics and even strong torque delivery make the Camaro hard to beat.

The Camaro shows its true potential when combined with the right peripheral components and porting. This includes a larger carburetor, a higher-flow intake port, and a tuning cylinder with larger transfer ports.

To take full advantage of its benefits, the Camaro requires pairing with a cylinder that has adequate port timing.

- Transfer port timing: 124° - 130°

- Exhaust port timing: 186° - 194°

- Shut-off times: 30° - 32°

Bottom line: The perfect exhaust system for a very powerful street engine, offering increased torque output and a well-balanced combination of a broader powerband and higher performance.

TIP: A properly adjusted carburetor and ignition are essential for a reliable engine. Tools such as a strobe light (#FS118600) and a degree wheel (#83002000) are available from the SIP store. Carburetor jets should be from the same reputable manufacturer, as different manufacturers work with different manufacturing tolerances. We recommend purchasing a jet kit from SIP or KMT.
