HKS 3304-ST010 Stainless Steel Header

Super Header Type-II

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 strong vacuum is created, to the contrary, there will also be strong pressure. Cylinder pipes are connected with Bypass Pipe to reduce pressure as minimum as possible. Rhythm of ?Pressure? and ?Vacuum? inside manifold is controlled.

Besides, number of bypass pipe, positions are designed to optimize for each engine characteristics. It enables to reduce pressure without change of vacuum. Therefore, there is no drop of torque as shown in the graph below. The engine will have Inertia Exhaust Gas Efficiency (Efficiency to increase 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 best result for street use from study of various data about a lot of engine characteristics and exhaust gas pulse. 4-1 Junction type has shorter length to the junction part and it is better for competition purpose that require performance only at high rpm range. But it has too less 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.

Did not include boot clamps but overall a quality made part

VERY EASY

Fast, Easy and free shipping

Fair prices, website was well organized.

All was great!!!

The experience was great thank you.

Had a hitch that no one seemed to have at a reasonable price.

cheapest price, multiple payment options, shipped very quickly overall good experience

I am so pleased! Autoplicity had the best price by far for the item I ordered. I was not familiar with them so having the Paypal option was perfect. Over all I saved $30 on an item that was close to $100. Shipping was VERY reasonable and quick. I ordered my item on Saturday. They shipped it right away and I received it on Wednesday. I am definitely an Autoplicity fan and will recommend them to my friends not to mention our mechanic. He found the item I wanted on sale through another major company. Just to double check, I searched online and Autoplicity blew that company out of the water with their pricing and service for the exact same item. Very nice!

easy check out and part look up system

Thank you.

thanks

I have place my order on line and I am very satisfied with your services , I wil recommend every one to purchase from you

great price but the shipping a bit high

Good prices and shipping costs.<br>They use FedEx (Yea!)<br>I'm not overjoyed w/partial shipments.

So far so good! Just ordered the parts I needed for my car which I've been trying to find EVERYWHERE without success, until I arrived at autoplicity. Great price, and with a lifetime warranty I'm assuming great quality. I have faith that when the product arrives I will be highly satisfied.

Recently ordered a cargo liner and I must say, Autoplicity had the cheapest price anywhere! Excellent communication and super fast shipping! Will definitely do business with Autoplicity again! Thank you for a wonderful shopping experience!
