Racing Exhaust SIP ROAD "Ban..
..ana" for Vespa PK50/S/SS/XL
large exhaust manifold
FOR RACE USE ONLY
The banana with more “oomph”! The SIP Road Banana has more torque and also a noticeable power increase compared to the more usual bananas. The additionally supplied exhaust down-tube manifold enables an exhaust belonging to the elite class of tuning options.
The, for the large frame, principle of additional manifolds has been adapted to the small frame exhausts. The enlarged cylinder exhaust port manifold connects ideally with the rest of the expansion chamber system. This offers both rideability and a more ideal gear change operation. The sound is agreeably decent offering itself for town and everyday use. Tours and even longer journeys are also possible. The exhaust is initially produced completely ready for use and not later cut open and re-welded.
Conclusion: A racing exhaust system identical in appearance to the original and produced using minimal construction tolerances, finished to an outstanding quality. Improved power and torque, heat resistant paint.
