vespa 244 acceleration | EXPANSION vs BOX exhausts | FMP - SolidPASSion |

[@愛迪生-x1b]

I don't know how much difference is between polini bix acceleration and sip's strongest box

[@FreakMoPed8]

polinibox is similiar to siproad 3, but a bit stronger in lower revs, so you can just take the sr3 values. i am gonna make this comparison in the future. its planned, yes.

Hello mista! Great video on the comparison! What is your advice for the best exhaust for a standard P200 with only "heart drill mod" on the air filter and a fast flow tap? Right now I have a polini expansion chamber but thinking to change for a Sip Road 3. Am I thinking right? Keep up on the good videos!😀

[@FreakMoPed8]

the polini racing? 😃 yes, good choice the sr3 👍 consider some. Otuning (light) it brings a big effect

[@manboxer7597]

@@FreakMoPed8 Thank you for the response and advice. I am thinking on perfoming an Otuning based on your amazing tutorial video. Just trying to gain courage to perform it! 😃
