Can a custom exhaust be fabricated from a slip-on from a small production bike like the Ninja 250, or other 4 stroke motorcycle or scooter, I've seen lots of slip-on that can maybe fitted to the Vespa 250ie or 300 ? I would think that as long as the Pipe is same basic size it may work.
I see brands like two brother, scorpion, Huski, and others that may fit our needs.
what you think
