Description:
HKS Stainless Steel Header (33002-BT001) Stainless Steel Exhaust Manifold Size : 42.7Mm - 50.8Mm - 60Mm, Style: 4-2-1
Feature
The Stock Exhaust Manifold Was Designed By The 4-2-1 Type Layout For A Better Performance For A Lower Engine Speed Torque. Because The First Catalyzer Is Mounted At The Exhaust Manifold, Exhaust Pulsatory Motion Makes The Exhaust Gas To Pull Back To The Pipe At Middle Rpm Range. It Causes A Loss Of Output By Behaving As An Exhaust Gas Recirculation.
The HKS Exhaust Manifold Follows The Same 4-2-1 Type Layout But Making It Without The Catalyzer Provides Both More Torque At Middle Rpm Range And More Peak Power For High Rpm. It""S Very Easy To Drive And Follow The Acceleration Well At Middle Rpm. And At A High Rpm, It Has Much More Power Than The Stock And Feels Clean Of The Na""S High Rpm Driving Characteristic.
With The Optional Hi-Power Spec-L Muffler And Front Pipe(No Catalyzer) Will Have More Power And Fine Na Sound.If You Want To Change The Exhaust Manifold(No Catalyzer), The ""Engine Check"" Lamp Will Be On Because Of The First Catalyzer Will Be Eliminated, But You Can Avoid This By Setting The Included Part. But If Used With The Front Pipe(No Catalyzer), Engine Check Light Will Be On. They Have Checked The Drive Performance For Fail-Safe Of Engine Check And Found No Problem. So Depending On The Situation, Muffler + Exhaust Manifold Or Muffler + Front Pipe Will Be The Options.
Main Material Is Sus304 For Better Performance At Circuit Use.
Adopted 4-2-1 Layout Design For Better Output From Normal To High Rpm Range.

Q: What are the different tubing options for headers and what is the difference between them?
A: There are two major designs for headers: the 4-2-1 design and the 4-1 design. In many cases 4-1 headers are designed for racing applications where the vehicle is being driven at or near redline. The 4-1 design maximizes top end power, whereas the 4-2-1 evenly distributes it throughout the power band. Either way, you're going to be getting more horsepower from a header.
Q: How do you install a header?
A: A header is a direct bolt-on. Simply remove the factory OEM exhaust manifold and the aftermarket header is put in its place. The header is to be attached the head of your vehicle. Remove all the bolts that hold the flanges in place and detach the factory manifold. The down pipe or exhaust pipe should be removed as well and then reattached once the header flanges are bolted back onto the head.
Q: How much does the material used to make the header matter?
A: There are two main materials that headers are manufactured out of: ceramic and stainless steel. Ceramic headers are less expensive, but are prone to cracking if they get to be extremely hot. Stainless steel headers are more expensive but are more durable and generally more stylish. Stainless steel headers can take any kind of heat you throw at it and not prone to cracking.
Q: What does a header do? Why buy a header?
A: An exhaust header is a performance product that replaces your factory exhaust manifold and improves an engine's performance by allowing air to flow more freely. The easier an engine breathes the more power it produces. Headers generally use piping with a wider diameter than factory tubing, which allows more air to pass through the exhaust system than factory. A header is one of the easiest bolt-on modifications you can make to increase horsepower, making an effective use of money if your goal is to quickly gain horsepower.
Q: For which vehicles is it necessary to buy a pair of headers? On your website are headers automatically sold in pairs for these vehicles?
A: When purchasing exhaust headers for a V-6 or V-8 engine, the header package is complete with two headers. If your vehicle is a 4-cylinder, there only a single header that is used.
