Puch Maxi Moped What Exhaust Would Fit On My Batavus City Moped?

What exhaust would fit on my Batavus City Moped? - puch maxi moped

I have two 1974 Batavus moped and one of them needs a new exhaust pipe (the tube that I am only a silencer). Who knows how pipe, which is the model for each vehicle to be used as a substitute? Puch Maxi will not work because there are less exhaust manifold, to me at an angle to the front wheel. Any help is greatly appreciated!
