  • Conical vs. Non-Conical: Conical manifolds have a tapered inner diameter that gradually increases throughout the length of the manifold and will produce more power than a standard manifold at the expense of decreased runtime. Non-Conical (or standard) manifolds have a consistent inner diameter throughout the entire length of the manifold and will provide smoother power delivery and better runtime than a conical manifold.
  • Headers: All manifold kits include gasket exhaust and springs. Shorter exhaust: gives less acceleration, but an increased topspeed. Longer exhaust: gives more acceleration, but reduced top speed. Conical exhaust: top speed higher, higher acceleration and higher fuel consumption. Cylindrical exhaust: top speed lower and lower fuel consumption.
