Give your Vespa a massive increase in torque and power characteristics whilst still keeping a low-profile look that can pass for stock in most situations. This fantastic unit is an innovative evolution in performance scootering exhaust systems. We have been incredibly impressed by the build-quality and performance of these pipes. The best thing is that these units give the performance of many larger, cumbersome performance pipes but they mount like a stock exhaust and do not have the limitations on ground clearance that many expansion chamber exhaust systems suffer from. These also do not interfere with stock centerstands or mounted spare tires, etc. This pipe fits all 125cc and 150cc Vespa largeframe and P-Series engines with and without cylinder kits. Ref: BGM1010TR
