Vespa PX Engine TUNING 🛵🔧 | Part 5 | Box Exhausts Test {English}

[@SAM-zt2uy]

Thank you, recently bought a PX125 that came with a Simonini exhaust I have now swapped to a SIP XL

[@marcustalman2756]

Best and fairest exhaust test I've seen from a great company, well done SIP 👍

🙌

[@danilozichittella2655]

Hi, great comparative! Would be useful to know the engine configuration and the port timing..

[@michaelhargarten5118]

Great test! You have the dyno numbers and the power curves to show stock to aftermarket exhaust difference's.

[@garys4756]

Im hoping to get my first Vespa this year and I'll use your videos for tuning ideas👍

[@cagatayguven35]

Such a great video. Amazing to see all characteristics of different exhausts.

[@SIPScootershopTV]

such a great comment! Thanks!

[@garyholub9914]

I'm curious about the other exhausts that are on your table but that you didn't test, there appears to be 3 (non-box) exhausts. How do these compare, I wonder?

[@MrUlfang]

Thank you for the work to bring information from the several products on the dyno.

[@blaps_85]

Great comparison. What is the complete configuration of this vespa in terms of cylinder and carb?

[@BusfreakT3]

Welches Setup hat den der Testmotor? Wäre ausserst interessant, inkl Steuerzeiten

[@dormobilegrandpa5342]

regards! the video is excellent! I ask, to change the original exhaust for one that has better performance, the jettings of the carb too?

[@lusciousthelock4861]

I would love the new sip 3 compared with the twin pipe Sport version. Do two pipes make any performance difference on a PX125?

[@borishuang5154]

More helpful for choosing a suitable exhaust, well done.

He quedado impresionado por lo bien que se ve en el banco de potencia las diferencias , Gran video. Entiendo estas mejoras serán compatibles y ó equilibradas a un motor original en todo, que primero mejorara un poco con el escape y luego más si se mejora filtro y retoca carburador, por ahí empezaré ya que mi vespa 200 Iris recién adquirida con 30 años y 8000 km esta original del todo y mi idea es hacer leves mejoras sobre el mismo motor . Gracias por el video y un saludo

[@paolorosselli1436]

Complimenti sei stato molto esaustivo così si capisce subito la differenza mi ha convinto il finale sip road xl complimenti ancora e continuate così grazie

[@richardshipman8399]

[@vespista_zd9580]

[@adamos9296]

[@CamerondeGrey]

Cool data experience

[@giovanniberuti8672]

Bel video. Ma montando una sip road 2.0 su un px 150, bisogna cambiare il getto del massimo?

[@danielepedrazzini5391]

Cosa mi consigliate per un px 150 originale quale scarico è migliore per saund e prestazioni sia ai bassi che agli alti giri cosa consigliate .Grazie

[@adipsanjaya1112]

Nice video sir.... greetings from twinspeed scooter indonesia 🙌😁

[@danielepe437]

Ciao mi consigli per il mio px 150 cc originale scatalizzato la marmitta migliore per farla rendere al meglio

[@waldemarkearney1015]

Great tutorial thanks 😊

[@SIPScootershopTV]

Thank you!

[@bartsimpson8616]

Sir i ned advice , bought polini box 200.2020 , for my Px 200 /1988 and i cant mounted on the cylinder stud it wont goes untill end like it should and has leak . What should i do ? there is maybe different studs longer or shorter or something else ? thanks ar advance ,

[@sattarkhan1848]

Dear can u reply me in commen box . Which mafler or silencer of engine . In very slow sound . No noisy in Vespas

[@rs3tuber425]

Excellent video!!! thanks for putting all the info together. I am looking for a box style exhaust, I already tried the lefty and the righty expansion chambers(Prima, broomstick, hotwing 226 and the simonize). I currently have a sit-plus which is great on mid range but it is a very old design, I need something improved.

[@SIPScootershopTV]

Thank you. You will feel a big difference to the old sit-plus design.

[@ha7v3y1]

Hi sip, What would be your thoughts running the sip xl on a px125 with a dr180 kit fitted and 21 tooth clutch 🤔

[@sergiopenaranda9491]

[@gintonicmunich]

👍👍👍

[@timthemod]

Hi SIP. I run an PX150 engine with 8 inch wheel standard cylinder what is better SIP 2 or 3? Thanks

[@SIPScootershopTV]

depends on what you want. If "better" means peak power. Take 3.0.

[@jfrorn]

I'm probably wrong but I think I heard the German pronunciation of exhaust as something like 'Auspuff' and I've never been the same since 😄

[@jfrorn]

What an awesome video, so informative! I'm so glad I chanced upon it!

[@1972dorian]

Gibt es das auch in Deutsch? Hab gesucht , aber nicht gefunden.

[@SIPScootershopTV]

diese Serie gibt es nur auf Englisch

[@adamos9296]

Any answer

[@bianchetfam7960]
