The DOC Race K Series Turbo manifold is for the more extreme setup looking for the potential limit of the vehicles engine. This manifold has seen well over 1000hp and is designed for peak-power situations. The DOC sidewinder manifold can still be used for “streetable” vehicles, but is solely designed to make maximum horsepower and allow you to fit up to a 42R or Borg Warner S372. D.O.C. still applies our elaborate porting process to complement maximum flow within ALL of their manifolds.
