There is one in every group,  this was the input of few Old School designers to come up with design, Not one of these designers have seen a Q pipe or a Hall Pipe, like I said this is a modified DCS-4 turned into a 5 who knows I might keep refining to DCS-6 till I am happy with the Low Mid High Graph, to be honest its starting to get a bit pricey not the pipe MFG its the research and dyno testing and just time devoted to this project.
 To be honest I will be making less than 10 pipes  and thats it!
I am working on pricing to sell these at a economical cost and I am mainly selling raw pipes but I will offer plated, just note there is alot more metal prep for me for plating, you might want to see if you have someone local that can do it more cost effective.
