Your opinion please on a Ypipe variation

DIYmirage, I have tried to picture how reversing the design would work. It would be like the Ramchargers setup. Also the huge hole is what we have eliminated from the original design. We simply have given the consumer the opportunity to have a short, complete, 100% exhaust route to the atmosphere, (which no one except No Weeds can do at a much higher cost) or you can have a turbulence free straight shot to the muffler.
