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? |

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'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

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

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. |

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: ![]() |

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. Mike |

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. |

We had a bout of unseasonably nice weather today, so I took the opportunity to slap the new exhaust on there.
Some pictures: Before - https://imgur.com/RMa7Mci After - https://imgur.com/EgmGMxv Close-up - https://imgur.com/6YCv3VM 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. |

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 ![]() ![]() ⚠️ Last edited by OrlTee on UTC; edited 1 time

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? |

Video of Exhaust
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[/quote] 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. ![]() Before
![]() After with matching paint and yellow chrome shield
