Stock Holes:
Middle hole = .132
Either side of middle hole = .120
Back holes = .092
Bottom hole = .078
The area of all stock holes = .05432
25% Enlargement:
Middle hole = .165
Ether side of middle hole = .150
Back holes = .115
Bottom hole = .097
The area of 25% enlarged holes = .08483
The area of the 8mm burn tube = .07787
By exceeding the area of the burn tube, you've eliminated the holes as a restriction, because they flow more than the burn tube.
Of course you've achieved the same thing. And it seems it works to great effect. My theory of increasing the hole size but keeping the hole sizes still proportional to each other is to hopefully preserve whatever flow pattern or swirl that mercedes was trying to achieve.
