No one ever said anything about the Macs muffler
But I did suggest a macs muffler as I pointed out that I ran one for example.

maybe with the baffle out thumbskull
I flew my Mojo40 with a 55AX and a Xoar 13x4 on the stock exhaust with the baffle for 3 months with GREAT pullout from a hover.
My AUW with the stock exhaust and empty fuel tank was 4lbs. 2oz.
I eventually got a macs one-piece muffer, not for more power, but to save 2.2oz.
Now is seems like it's on more power but it's just the 2oz. saved. Only got a 100 more revs on the top.
But again, it's not the top end that we are concerned with, it's the midrange throttling.
