I think you are forgetting where the N54 is headed these days. The ownership group of these cars is getting cheaper, and cheaper. I mean shit we posted a breather on here for under $200, and the first thing that happened was for people to bitch about price. You should have made your manifold two years ago when the market was open. Now you have to compete with all this stuff on the market. Is there any question you manifold is light years ahead of this in quality, and design? Absolutely not, problem is, the average buyer will be running 500-600WHP, and the gains between the two will be marginal at best. Shit I would be surprised if either showed gains over a stock manifold at those levels. So for no difference in power for 90% of the buyers, its $700, or $2500. Its obvious who will get most of the sales, hopefully you didn't spend too much designing, and building your manifolds.Support the American dream, buy from China.
Sharp Customs is a powdercoat shop, actually the powdercoat shop that does all my powdercoat for my products, about 5 min from me. He imports and sells these junk manifolds for all different applications by the truck full. Interested to see results as well.
