SITO Plus Exhaust (Performance); P125X, PX150, Stella 2T

Sitoplus performance exhaust for Genuine Stella and vintage Vespa VNX P/PX 125 and VLX P/PX 150 scooters. Remove the muffler bracket, and this will fit Vespa Super, VBB, VNB, Sprint, and GT scooters, too. The best bang-for-buck ratio of all the pipes we sell. Gives a good increase in power and torque, especially in the midrange. Improved acceleration and better power for holding speedup hills, into the wind, and with a passenger, as well as a slight improvement in top speed. Sounds great too! NOTE: Don't forget you'll need to rejet your carb! A good starting point for stock engine is a 55/160 idle , 160 air , BE3 atomizer and a 100 main jet . Looking for more performance upgrades? We also carry a GL/VBB basic performance kit and a Stella/P125/P150 basic performance kit that include this pipe!
