The Sito Plus muffler for Vespa P125X-PX150-Stella and other 125-150cc large frame Vespas. Increased torque, top speed, and better acceleration. Installation is easy, this a simple bolt on exhaust.
A perfect performance exhaust for someone looking for improved power with a stock look. The sound level is slightly increased but still quite reasonable.
NOTE: YOU WILL HAVE TO RE-JET FOR THIS MUFFLER. JET NOT INCLUDED.
All jetting quotes are for 100% stock scooters without any air flow modifications, at sea level. See our SI MAIN JETS to purchase the desired jet.
Stella 2T: Stock is 94, we recommend a 98 with the Sito Plus exhaust. 2005 Vespa PX150: Stock is 98, we recommend a 102 with the Sito Plus exhaust. For other Vintage Vespas (125-150cc largeframes): we recommend going up 2 jet points from where you were originally.
