Al (diablo) is building me a 219cc polini and i don't want to use a ring ding expansion but also don't want to strangle the motor so thought this would be the best of both worlds.
Anyone used one or know anyone who has.

Personally, I'd ask what Diablo thinks. If he thinks it'll suit then crack on.

I guess it's down to how he's building the engine, is it being set up and geared as a touring or a racing machine?

I think he would like me to have the expansion but i dont like the look, noise and they all break

save yourself a hundred quid and get the SIP road instead. a few of the lads have them on standard P200"s and they work well.

do they?

I think you're after the unobtainable personally, there's no "best of both" in the exhaust game, if diablo believes the expansions the way to go, I'd do it personally, but it's your money.

Those sip ones are just a good old sito plus and I don't care whats done to the inside, it'll strangle it compared to a proper expansion pipe. The question is, will you be happy with that?

The Sito+ is a copy of a PEP, isn't it?

Hasn't Doncaster's other engine builder just invented a copy of the SIP road exhaust? That could be another option.

There's someone in Sicily builds something similar too. You'll have to google that yourself though.

the sito plus and the sip road are completely different pipes.

the sito plus is a copy of the t5 pipe with what sounds like no sound deadening matirial, a hate them due to the noise they make but they let the t5 rev out better.

the sip road is a standard p2 pipe with cones added to make it into a clubman, its so quite that it makes riding every day a joy (unless you wear a tracksuit and like revving the crap out of your scooter in the street for no reason, in which case you will hate it)




i have used both and the difference that going from a sito plus to a sip road was a real surprise, with a power band and plenty of grunt.

no disrespect to diablo or any other tuner but you tell the tuner what you want not do what the tuner says, thats how so many people end up disappointed with a race engine that will not pull their mrs and pav trailer on their touring holiday.

train driver has a rz right hander and a sito plus so i say try both, get carb settings for both then just swap for the one you want to use.

the rz has quite a nice deep tone on a vespa so he could be happy with it

^what he said..don't see a 5 cone semi expansion pipe going into a sito plus , and they rust to dust within a year . The sip road is a good bit of kit, works well and is well worth the extra couple of quid over a sito.

Is it? I've never heard of PEP til now to be honest and the Sito plus has been around for over a decade so I can't comment on who copied who? On saying that, didn't I read on the original link that PEP take a sito plus and remove the innards etc?
So why would pep take a copy of their product to modify?

Doubt they made a copy, they may have furnished one that's got similar qualities though :bigsm:
