A couple years back, I remember reading about a balance pipe that was supposely better than an X pipe and H pipe. Kinda combined the two designs. I see MAC makes a Pro Chamber, but that wasn't that name of it. I thought it was
something box. Both pipes went into a rectangular shaped box and both exited out the other side. Was doing some searching on it but can't seem to find any info on it. Does anyone remember anything like it or know of another product like it?
