Modern Vespa

If there happened to be a performance exhaust for the GTS and GTV, in chrome or black that was offered by Piaggio, an Official Vespa performance exhaust, with a real Piaggio part number, in official Piaggio packaging, Made in Italy, how much interest would there be if it was under $300?

By "performance" do you mean it would actually add HP-or just sound and look really good?

Either way, it looks interesting... Are there any pics of this "theoretical" exhaust on a 300?

Same performance as an Akra, but less noisy? Yes, I would be interested.

I assume it still would use the graphite bushing, would there be any weight savings? If it was at least a little lighter, and helped any with performance with out lots of noise, I would be interested. Would be nice to see what it looks like on the scooter. Thanks

I would if it was louder

I'd probably buy one, matter of fact if you want a tester/feedback sign me up and I'll be a ginny pig In chrome to match my GTS' motif

If it added performance and was louder, I would definitely buy one.

Best answer...

I'd consider buying if in black and quieter. I hate loud pipes.

Have no use for louder but would like lighter than stock because it's unsprung weight.
Improved performance would be a bonus.

Would like to see this exhaust mounted on a GTS. (Pics)

CD: I'm with you. Noise is noise.

where will they hide the "Made in China" sticker?

Forgive me... is that supposed be a picture representative of the final product?
The stock GTS/V exhaust is pretty long. Something like 18-20" of primary length. You cant see because its tucked up in the boat anchor stock muffler.

I will buy one I will be checking your site since you can't get me the exhaust I want

OEM Piaggio Aftermarket Style Performance Exhausts are here and posted in the Sponsor's section.

This is an original Piaggio accessory, and it fits all GT, GTS and GTV models.

It is very hard to find stock photos of this exhaust mounted, but I did manage to find this of the chrome one:

Ooooo. I like it.

How many of the chrome units do you have? just want to make sure I don't fall asleep and miss out

Performance? Any figures? Or is the only performance benefit due to the reduced weight?

Sound? As loud as an Akra?

A little more info would be great.

It looks very nice, but hangs a bit low for my liking.

It's designed for people who aren't riding wheelies on their GTS.... From what the company who made it for Piaggio says, and keep in mind that they say this pipe is for 125, 250 and 300cc GTS models, they did a bit of dyno work in developning it and it is supposedly good for .9 to 2.4 horsepower, depending on the model, etc... Once you put on the Malossi cylinder kit and got used to mods that make a third more horsepower than stock, it's hard to get as excited about one or maybe two...
I read what you wrote about the Polini 6 roller, the variator everyone sort of passes over, and I put one in my GT. I like it. It doesn't have the explosiveness the Malossi has, but it seems to have a better top end. The bike just keeps going until you run out of room. I am seriously considering it for the next Scooter Cannonball, and i got one for OAD and his potential project.

The Polini variator came out better than the Malossi in the Scootering magazine comparison tests, adding 2 hp over the whole range compared to the Malossi's 1-1.5 hp., but that was many years ago, and both variators have changed since then. I believe the 9 roller Polini is vey smooth.

With this being a slip-on system using the existing header, this would still require the graphite exhaust gasket?

Also - any clearance issues with Vespa Rear crashbars?

Looks like they are pretty nice and well priced.

Got one for the BV500?

I would if it is not too noisy.

They seem to expose the bracket too much though.

Anyone try the product yet? Any advice or pros/cons after replacement of stock exhaust with the Piaggo performance exhaust appreciated. I like the idea of reducing some of the weight from the back of the bike while using an OEM part at an reasonable price. Speed and performance of the stock bike are fine for my riding style.

I got one, but haven't installed it yet. Waiting until the weather gets above freezing again. Will post some feedback once I have it on there.

Nice! do you have it in black or chrome?

I got one of the Polini 6 roller variators and rode with it for a couple of weeks. I was very impressed with the Polini when I put one in a BV250. Then I compared it to the Malossi and a CVT FR4 variator in my Vespa. I used 13 gram weights in each of them, so they would have to work to hit the rev limiter but could spin up into the powerband. In same day back to back testing, 50 miles or so on each, mostly wide open on the freeway, the Malossi was almost 2 mph faster than the CVT FR4, and the Polini was the slowest of all. If you use them with the weights they come with, the Polini would probably do better, because it's got lighter weights, but if you put the same weights in the Malossi, it will perform better. I still like the CVT FR4, but I really expected it to be a lot faster than the Malossi. The other places the Malossi made a difference was in head winds and slight inclines. I didn't drop as much speed as with the Polini.

Chrome, of course!

We had a bout of unseasonably nice weather today, so I took the opportunity to slap the new exhaust on there.

I ride this thing every weekday and most weekends, so I'd like to think I'm familiar with the sounds the scooter makes. Having said that, I can barely pick up the difference in sound between the old exhaust and the new one. The new one is slightly more...throaty? I'm not quite sure how to describe it. At any rate, it's not going to magically make your Vespa sound like a Harley.

In terms of performance, it seems like the scooter is smoother on acceleration, but I might be imagining things. I only took it to the grocery store and back after putting the new exhaust on, so I can't comment on how it performs at higher speeds.

Installation was a cinch, and I say this as someone who's really not mechanically inclined. I didn't time myself, but it probably took less than an hour.

Thanks for the pictures. Nice looking scooter. I like the look of the new exhaust over the OEM exhaust. Can you determine any difference for better or worse from the reduced weight on the back of bike?

Despite the considerable difference in size, I think we're only talking about a few pounds here. Didn't pick up on any handling changes while I was riding.

Picked my bike up from the shop today with the new exhaust in Chrome installed. The sound to my ears is softer deeper rumbling tone than the original OEM exhaust in my opinion (A lower noise volume is a benefit for me)

I did not notice a performance boost rather a smoother transition when engaging the throttle and releasing the throttle. My bike only has 700 miles so could be with the system reset and the new exhaust the bike feels smoother all the way around.

I can feel the slight weight reduction when placing the bike on the center stand and backing the bike in to my driveway as the I have go up a slight hill backwards and being a woman any addition to make the bike easier for me to maneuver is great benefit.

Note-The exhaust is made by Spark Exhaust Technology manufactured in 2014 from my research for Piaggio to fit the GTS/GTV Vespa as an OEM Piaggio accessory

Nice looking chrome exhaust to match the wheels. Should last way longer than the original. Exquisite.

Thanks for the post! I will definitely be getting one for my GTS

Would like to see a video of it on a gts. I've got my eye on Black Widow

There is one Chrome one and a couple of black ones left. I've been trying to get more, but to no avail at present.

Does this just replace the muffler can from the gasket rearward?

And is the graphite gasket still needed?

OrlTee, Tell us about your custom painted helmet. Brand and how you painted it. Also, how do you like the new exhaust since you've had it for a few weeks now? Can you make a video so we can hear it?

Thanks!
Miguel

Hi Miguel

I am enjoying the new exhaust, sounds great looks great. I am not a speedy rider but did get the scooter up to 75 mph on a straight paved road based on the speedometer. The scooter accelerated very quickly and smoothly with plenty of remaining power and speed available if needed, I did not have the throttle wide open at the time.

Acceleration at take off seems to be much smoother too me and bike easily reaches the speeds I require.

See the attached video for the sound taken after a short ride, the baffle is installed so any that want a louder exhaust you could remove it.

My local dealer was able to have the helmet painted to match my scooter at my request. The brand is a Bitwell Gringo S Limited Edition
