Replace exhaust on 912ULS

I am needing exhaust for my Rotax also . I seen their web site and like the look of their product . However , I sent them a message and have not yet heard back . Is there any other good sources for exhaust systems for the Rotax . 

We ended-up not buying a new but repairing the existing one instead. We found that the kind of repair is exactly the same applied to car/bike exhausts and there're shops specialised in this kind of repairs. Clearly the cheapest option in case it applies. In our case they did a full muffler cut to reach the breach, then repaired it and closed it again. All these for less than $50 and flying silently since then ;-)
