Puch Jamarcol exhaust, its street name is the \"Jammy\". The Jammy is a super cheap basic pipe for your entry blasting needs. This one has a removable baffle, so you can slide this chamber onto a bunch of different headers. IE Minarelli, Batavus, Morini, Derbi, Tomos, and basically any bike you want to fasion a cheap chamber for.

DOES NOT COME WITH THE HEADER!! this is just the chabmer!!!

For a Maxi you will need a slight bend out of your pedal arms to get this to clear.
