You are welcome

It may help, as long as is not aligned with the exhaust pipe.
Try thinking like you were the exhaust gases traveling the easiest path between high and low pressure.
Would you go through those holes on the wall or through the center of the main tube?

The attached schematic belongs to real Yamaha engines.
Notice how the flow is forced to follow a path with successive expansions.

Yes, heat and epoxy resin don't get alone.
