SITO at SIP Scootershop
You only have to read the enthusiastic comments on the Racing Exhaust SITO Plus for the Vespa PK50 to understand the quality SITO offers. The Italians reproduce the original exhausts. They have a throaty sound, look good and sometimes even produce a little more power. And most SITO exhaust systems even have an E-number.
Conclusion: SITO offers reasonable quality and durability for replicas of original exhaust systems.
