350Z HKS Exhaust Manifolds

【STAINLESS EXHAUST MANIFOLD (for NA)】

HKS Exhaust technology, which is know-how of long time development, targets to pull out 100% engine performance with the exhaust manifold. A lot of different approach were tried for each vehicle to keep performance for middle rpm range and to improve horsepower at high rpm.

Reduced pressure with Bypass Pipe (Racing Header)

When a strong vacuum is created, to the contrary, there also is strong pressure. Cylinder pipes are connected with Bypass Pipe to reduce pressure as minimum as possible. The rhythm of “Pressure” and “Vacuum” inside manifold is controlled.
Besides, the number of bypass pipe and positions are designed to optimize for each engine characteristics. It enables to reduce pressure without a change of vacuum. Therefore, there is no drop in torque. The engine will have Inertia Exhaust Gas Efficiency (Efficiency to increase the horsepower of NA engine) and flat torque characteristics, which enables easy drivability.

Advantage of 4-2-1 Straight Junction (Super Header)

HKS selected 4-2-1 junction design that has the best result for street use from the study of various data about a lot of engine characteristics and exhaust gas pulse. 4-1 Junction type has a shorter length to the junction part and it is better for competition purposes that require performance only at high rpm range. But it has too little torque at low rpm range for street driving.
HKS’ Straight Junction Design accelerates exhaust gas with exhaust gas pressure and it pulls out combustion gas. Exhaust gas efficiency is improved with the design.

HKS Exhaust Manifolds are designed to be precision crafted units that improve exhaust flow and efficiency compared to restrictive factory manifolds. For naturally aspirated applications, these manifolds are the first step in developing a completely new exhaust system. HKS Exhaust Manifolds are made from either tubular stainless steel, ductile-iron, or cast-iron, and have been rigorously tested.

Code No. 33002-AN001

HKS Stainless exhaust manifold to pull out the latent power for Fairlady Z/Z33.

Feature

It’s compliant for 6MT and 5AT of Z33.
We have analyzed thoroughly on flow speed and resistance with flow bench and we could reach a great improvement on performance. Especially from 3500rpm to 5000rpm torque improvement make driving much more exciting.
Better appearances and more strength with Tig welding.
The original thermal insulation plate is standard equipment and also the thermal tape for the absolute measure for heat.
