Newbie here...I am planning on putting a kit on a Sachs Prima but can't seem to find a performance pipe. Figured I would butcher the stock pipe, sawing it off right where it begins to flare maybe 14" from the exhaust port and then put a silencer on it. But before I butcher a nice stock pipe, I thought I'd ask you guys to see what you've done. hate to chop a pipe in nice shape...Thanks.
