I wonder if a collector ring with much more volume and an exhaust stub would help. There's lots of room. I'd also have a few cooling fins built in.
My last post assumed that the sub piston induction was still present, which the original post obviously states that it has been eliminated, but most mufflers on 'racing' designs do rob power regardless due to back pressure.

Simply providing a greater volume for the exhaust gases to expand into will help but I highly doubt that finning the collector will do much at all.

Exhaust collectors also collect heat and in my experience this can be a problem. But that was on glow and this is diesel which doesn't mind heat as much. Thanks for the link. I searched for Marz and all I could get was Mars.
