will this 70cc kit fit on my piaggio zip 2000 model 2t with the catalatic exaust , this has been took off and now has a tt pipe on ? what power are these kits capable of producing and will it make the power any difference from the standard 50cc cylinder ? http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 5751wt_932
Link isn't working for me however I would recommend a named brand such as the Malossi Sport. Have a read through this: http://www.scootershack.co.uk/scooter-tuning/exhaust-barrel-matching-guide-t2948.html See what matches your pipe and go with that!
