We provide two manifold models:

  • Racing-type models
  • On-road-type models
    (meets dimensions of standard manifolds)

Thunder's SUS304 stainless steel manifolds are low-noise and sturdy. With 2mm-thick tubes, unique in-house design, and HKS Dynojet horsepower test certification, we guarantee the superior quality of our manifolds and their extended operation lives!

Features:

  • Stainless steel assembled manifolds:Durable and rustproof
  • Stainless steel exhaust pipes:Easily welded, sturdy
  • Thick stainless steel tubes:Low-noise and with longer operation life

Fuse welding is better than pulse welding:
Standard pulse welding simply welds manifold pipes together. But the weakness is that the pipes become thinner after welding, with structural changes and a shorter operation life. However, welding with the addition of fusible material the same as that of the pipes does not compromise pipe-wall thickness, but rather strengthens and extends durability.

Comparing 4-2-1 to 4-1 manifolds:
Guaranteeing high performance, the 4-1 manifold meets the latest world trend. Each engine's parameters must be known to design a 4-1 manifold. A short manifold is designed to minimize torque-loss that usually plague original autos, while four equal-length manifolds or headers are designed to maximize performance during mid/high rev ranges.

A 4-2-1 long manifold causes torque loss in engines due to insufficient re-pressurizing and large pipe diameters; and cracks easily due to having too many connections.
