The new SIP Road XL for PX125/150 and Stella 2T Vespas.
Our German allies at SIP have really developed an amazing product with this exhaust, combining expansion chamber performance with stock looks. The silencer portion of the exhaust is fed by a 10 piece free flowing expansion chamber header. This powerhouse exhaust is the closest you can get to an expansion chamber while still having a relatively stock looking exhaust. It's even got the exhaust spring mounting tabs welder to the header so you can spring mount the exhaust with ease (springs included).
The "Road XL" exhausts offer significantly more torque without adding much more noise. They are great for city driving or long-distance touring and a step up performance-wise from the SIP Road 2.0 exhaust.
It's a racing exhaust pipe with original aesthetics and a high-quality heat-treated black finish. These exhausts are built to last and ultra easy to install.
Manufactured as a direct replacement for Vespa PX 125/150 and Stella 2t engines but can also fit to Sprint and Super engines with modifications to the mounting bracket of the exhaust.
You will need to upjet your main jet in your carburetor 4-6 points. See the related items below for jets and more exhaust options.
