Neukin Motor Development uses nothing but the best. Their head flanges are CNC milled out of solid steel in Texas, not laser cut or plasma cut with heat. Those methods leave a dirty and rough edge not giving you the quality you deserve. Their wastegate flanges are bought direct from the manufacture that makes your wastegate. They are a brilliant stainless CNC milled flange from TiAL in Michigan. The wastegate flanges also have threads making your install simple and without the need of nuts. Third, our T3 flanges, also CNC milled stainless are direct from Oregon. Thats just materials... each manifold has been hand welded over the past three years here in Indiana, USA by Alex Neumann the owner of the company. In the past year we have added Derek King and Austen Snyder to our Neukin welding staff. With 500+ manifolds sold and the sucess of the company over the few years your sure to be running one of the best products out there. Now compare that to manifolds that cost $600 or even $1200 and you wont see the same. If your going to spend hundreds on a turbo manifold dont you want it to be the best?
