SITO repro exhaust - Vespa Rally 180 (VSD1T) / Rally 175 CH (VRD1T) - true to original transverse position

Reproduction of the rare, transverse standard exhaust for the Vespa Rally 180 (built around 1968-1973) and the Swiss Rally 175. Matches the smaller 180/175 flange on the cylinder. Ideal for true-to-original restorations and roadworthy setups with a classic look and fit.

Important: 180/175 flange vs. 200/PX200

The Rally 180/175 uses a smaller cylinder flange than the later Rally 200/PX200 models. 200cc exhaust systems only fit the Rally 180/175 with an adapter flange. We have a suitable adapter/conversion nozzle in our range (see accessories). An alternative
Rally 180 / 175 CH True to original lateral position Fit as standard Heat-resistant paint finish High quality repro - immediately available

Characteristic

Acoustics close to series, unobtrusive appearance
Repro geometry for Rally 180/175 - no modification to the frame necessary

Compatibility & notes

Rally 180 (VSD1T, approx. 1968-1973) - direct replacement on the original flange
Rally 175 (CH) (VRD1T) - variant for the Swiss market with 175 cc
Engine predecessor of the Rally 200; different manifold flange than 200/PX200

Model/year of manufacture information: see type code/production. :contentReference[oaicite:2]{index=2}

200/PX200 exhausts have a larger flange - on 180/175 only with adapter nozzle
Adapter solutions are available on the market (e.g. connecting pieces/adapter kits)
Conversely, the 180/175 exhaust does not fit on 200 cylinders without modification

FAQ - Frequently asked questions

No - the flange of the 200cc cylinders is larger. An adapter is required for 200cc systems on 180/175; this exhaust, however, is made for the smaller 180/175 flange. :contentReference[oaicite:4]{index=4}
Like the original, the body is cylindrical and installed transversely. Painted in heat-resistant paint for a look close to stock.
No. The exhaust uses the original mounting points of the Rally 180/175 and is fitted in the same way as the standard system.
Compared to worn old systems, a tight, new repro usually provides better pulling power and quieter running noises - but the focus is on originality, not tuning.
