Re: Vespa Pinasco 177kit- Quiet Exhaust? Tech Help Please!

Loud pipes save lives!

i recently installed my sip exhaust, and i mostly agree... i don't think it's much quieter at idle, but it's quieter then a sito+ at speed. if you want quiet and performance, you just might have to trade in your scooter for a big cc 4 stroke scooter.

I have an SIP exhaust on mine and it is JUST slightly louder than stock ( why I like it). Most other exhausts are far louder. The Sito+ is louder by a good bit. Double check to make sure you have it on tight? no cracks in a weld or anything?
