This is a full expansion chamber exhaust from Malossi, one of the great makers of performance parts for vintage Vespas. This expansion exhaust is for those that need as much horsepower as possible and who have already invested in a cylinder kit. The design moves much of the pipe right under the cowl so for bikes that normally carry a spare there, that will not be possible with this pipe. This pipe fits all the 125/150 Vespa largeframes but is not really recommended for 8 inch wheel bikes because of the low ground clearance, but if you don't plan on taking left hand turns... enjoy.
