Good point Archie.
But sometimes it's difficult to get a engine builder to do what you like as they have their ideas too. Where as when you are DIY you do as you please and want.
I personally don't think Meercat can replicate the sound of a blitz. It seems the design of the backbox is unique to a blitz.
Btw I'm friends with Meercat and support them 100%.
But what sounds you get from Meercat is unique to them too.
