Did anyone ever try building one of these "pressure wave termination boxes" or "resonator box"........it seems to me that is the most important part in this article, so why is the damn picture so small you cant read the design specs for this box?
From what I can gather, with a dual exhaust system, each box has to have an internal volume equal to your engines total cubic inches, the inlet pipe should also protrude 2" into the box, and the box should be round in construction and designed to have a smooth flowing exit back into your exhaust pipe.
Anyone have any info on this box and some real world testing results????
