After breaking a second stock header pipe attached to a Leo Vince exhaust, I'm in the market for a complete new exhaust for my GTS.
I'm leaning to trying out the Giannelli Iperscooter, but after much inter-web serching, I can find little information. It appears to be well engineered and well built by people who know performance scooting. Perhaps the best info I've seen was from a MVer "juan" from Florida who installed one and reported after 100 miles: see https://modernvespa.com/forum/topic36678
I'd be very interested in getting more feedback from owners of this pipe, especially some who've lived with it a while. It seems to fit all of my criteria below:
1) it's not the stock exhaust
2) it's a high quality actual performance unit that doesn't break or break my scooter - rules out Scorpian and Prima from what I hear
3) comes with a complete SS header pipe with O2 sensor bunghole and attaches directly to the exhaust port
4) it's not excessively loud - rules out PM
Please any feedback is much appreciated (other than telling me to go back to stock - I seem to get prickly at that).
Thanks!
