Despite searching everywhere, including the Zenoah manual, I cannot find a def. answer on this. Do the G-45 and G-62 share the exact same exhaust pattern?? The manual shows them using the same #muffler gasket so I would assume but wanted to make sure. Reason is I have found a good deal on a header for a G-45 and if it fits, I need it for a G-62.

Thanks!

They are pretty much the same engine except for the bore and stroke

Yes....but that doesn't answer my question specifically.

The bolt pattern maybe the same but the G-45 muffler is mounted on an angle and for that reason it has an angled shaped spacer on the muffler. The G-62mdoes nopt have the angled spacer. Stuka Jon

Only difference in these engines is the jug bore and stroke......muffler, magneto, carb, even the prop nuts are the same..

The bolt pattern is the same, BUT using a G-62 muffler of any shape on a G-45 makes for a cockeyed muffler. Especially with a Pitts style.
