Here is a clip from my Stella I just finished. I still need to tune it a bit. But wow what a huge difference.

Great video. Nice to hear and see the take off and shiifting through gears.

It does appear to be a bit more crisp and spunky than stock.

I have a friend that loves the sound of the Prima pipes. I imagine that one of those new Boomstick! pipes sounds similar.

The Malossi kit has some fierceness to it, but I think a 60mm stroker should be considered as well in order to give extra grunt until the cylinder hits it's stride.

I want that done to my scoot bad. I'll wait until the warranty runs out however.

I wonder how hard it is to get the kits in canada. probably just have to pay some obnoxiously high shipping fee and customs.

I doubt my dealer will do this either, so I'll have to find a decent mechanic to help. how much were all the parts for this upgrade?

You could always drive to Buffalo and have a shop there do the work.

potentially yah. the highway there is too fast for the stella so I'd have to freight it over, but that might offset the shipping and customs which really suck.

dealers dont' usually add these mods do they? being that it sort of goes against genuines' warranty agreement etc. there's plenty of good mechanics in toronto, I'd just need the kit here.

If you want to void your warranty, most dealers will be happy to help you.

You could also, just order the parts in buffalo and have a local shop do the work. would be one way to get around customs... not that i advocate violating the law... it's theoretical, ya that's it!

This modification was done to a two-stroke Stella. Your sig indicates that you have a four-stroke Stella. If this is the case, those modifications will not work on your bike. You will need a Polini 165cc kit, possibly a carburetor and an exhaust system designed for the 4-strike Stella engine.

Nice Catch, I totally missed that.

right, it sounded like a 2 stroke, but I've heard pipe upgrades that sort of have that same character so I kind of assumed it was a 4T for some reason.

oh well.

i'm sure most of you have already seen this, but for any who haven't and are considering a new pipe:

it obviously is from 226, the creators of the pipe most served by this graph, but it's my understanding that they're honest folk...
bald john works with them, and theyve done more research and testing on the stella than anyone.

The shape of the Hot Wing curve makes sense once you've butt-dyno'ed one; it has a nice punch when the pipe comes into the RPM range it's tuned for.

Bald John is a stand-up guy, I've worked with him on several bikes in the past.

Yea what surprises me the most is how well my cheapo sito+ does relatively. I like the stronger initial throttle since I'm a heavy city rider, and I like how it doesn't bottom out at the top.
Its unfortunate they didn't dyno the sip road as I've heard its like a much better version of the sito.

The SIP Road hadn't been seen in the States when 226 and GGR did the "Project Stella" article for Scoot! magazine. I finally got my hands on one just before last year's Fall Classic and once I had tuned the bike, I loved it. Perfect stealth pipe, not as pingy as a Sito+. The Road is based on a stock Sito muffler, but has a divergent cone built into the downpipe. As a result, it's throatier than a Sito+, has measurable grunt in the middle of the powerband and will rev on as high, if not higher than the Sito+.

I think the Sip Road is based on a German pipe called the PEP 2.0. The PEP was built from an OEM Piaggio muffler, so it has thicker stampings and deeper resonance characteristics. The divergent cone doesn't look as cleanly formed on it, though. There was another pipe, the PEP 3.0, which used the OEM muffler from a Vespa T5. I'd love to see a SIP can based on that, but I doubt it will happen. The Sito+ is a clone of the Vespa T5 exhaust, and I doubt that the market would pay extra for a reworked Sito+. PEP 3.0s are hella pricey (~ $300).

I like the SIP sound on my pretty-darn stock P200; it's throatier and sounds great at high RPM. Not much louder than stock. You feel the pipe more than anything.

I put one on Howardr's 175cc Malossi stroker and it seems to work well. Not sure if it's the long stroke or the Malossi kit, but his bike gets a bit of a dirtbike sound at higher RPMs. I'd have to record it for an accurate representation. Howard loves it and I dig it, but JohnKiniston hates the sound. He's biased to the sound of the Sito+ and the Prima. Some folks just like pingy pipes, I suppose. I prefer throatier pipes. One of these days, I need to try one on a rotary valve 150 and see if it sounds similar.
