My 3300 is SN 410, and was TIG'ed, no problems so far at 82 Hrs. TIG repair is a challange due to thin material in muffler vs thicker stack. Repair, see Jabuiru.AU website, is easier if done before cracks appear. I haven't heard of anyone with dual mufflers. I have seen a straight pipe extension use by some Sonex aircraft with the single muffler inlet for each side. I also noted at Sun-N-Fun last week, that a different configuration muffler with seperate inlets for each cylinder has been developed. That enginge was configured for a Europa.

A friend has the same muffler and has had problems with the MIG welding. MIG welding did not hold and he had it TIG welded. Problems come about when the new welding is not exact and the two exhaust pipes are not perfectly aligned. So, I was considering a dual exhaust system with each exhaust pipe connected to it's own muffler. Has anyone any experience with a dual exhaust system for the Jabiru 3300?

I'm happy to hear that you have over 80 hours on yours with no problems. Perhaps I'm overly concerned because of the problems my friend had with the MIG'ed weld. -----Original Message----- From: owner-jabiruengine-list-server@matronics.com [mailto:owner-jabiruengine-list-server@matronics.com] On Behalf Of Jim Stone Subject: RE: JabiruEngine-List: Dual Mufflers --> JabiruEngine-List message posted by: "Jim Stone" Have you inspected to see if your muffler was MIG'ed?
