| Message | :You even admit that my manifolds "likely flow better", but dismiss them because standard 15-yr old downpipes won't work on my new design.  That is a separate issue whose merits could be discussed  another day. I was the one who said that they "likely flow better", and I don't dismiss their performance potential. However, unless you make comparable downpipes to what will soon be available from Greg Dupree, the potential performance gains from your "likely flowing better" manifolds will be moot. You absolutely must take a systems approach to this, otherwise you risk compromising the benefits of your manifolds by using less than optimum supporting components. You choose to not believe the hype over split downpipes. However, most everybody else DOES believe in the performance benefits of split down pipes.  By not offering a comparable solution, your are severely limiting the market appeal of your product. Most people want plug and play parts. This is the market segment that Mike is after. Apparently you are choosing another market segment
