We received some complains about 1 piece muffler 60-90(usually for front facing engines) of Zimmermann.
first, i would like to inform that from now and on, there is no 1 p muffler for 60+ size in production, only 2p.
in case you had a problem with 60-90 size 1p muffler, and there was any damage which was "naturally" created, not by crash or any other reason, you can exchange it for FREE, ( the decision of the damage result will be made by factory only!!!) it is possible to see if the damage made by vibrtation, or other wrongly used situations
if you have a new muffler, and you willing to exchange for 2part newer muffler, or even if you have an used muffler and it cracked (again, for reason of production and not misuse or crash) you can replace it for a difference of a small fee, i suppose it is 25-30$
this decision was made in commom to help people resolve the problem.
More then that. if you have any problem with the muffler, it is possible to repair it, not like Aluminum, the Zimmermann mufflers are moslty repairable, so any problem, please inform us.
Please note, that only Zimmermann factory will decide if the muffler was damaged by wrong usage or else.
its a big effort we offer, but please use it in real cases.
if you have any questions, please mail us.
i hope you will continue enjoying those products.
Enjoy and Good luck!!
