So I stumbled across some people on the forum talking about helix exhaust, and so I went and looked up some of the stuff they were talking about and I must say that I really like the idea behind the design of the exhaust. My question, does anyone know why they quit the prototype build? I mean I think it sounds much better, looks cleaner, and just seems like it would perform better. But is there something I am missing? Someone prove that the more known slow 90 degree splitting T to two mufflers and then the other 90 degrees to the tip with an upsweep bend to the tips better? And does anyone know the design measurements for this exhaust? I would love to venture to get pipes bent and me weld them all together for a system like this. Or if some company is making replicas of these on the down-low? Just curious. Thanks.
