Stainless Steel Manifolds, Headers For Ferrari Dino 308 Gt4

These manifolds were designed to : 1) Increased flow(+43%) over theoriginal restrictive design. We achieved this with larger pipe diameterand a unique 4 into 1 merge collector design. 2) Increased power(+19hp) and increased torque(+17ft/lbs). 3) Reduced weight by 32%. 4)Reduced engine bay temperatures over the original manifolds (-7%reduction). We achieved this with a high tech thermal coating thateliminates the need for manifold heat shields.
