Basic Bolt ons: Exhaust Headers
In this section I will go into detail describing the kinds and brands of exhaust headers.
When it comes time to choose an aftermarket header for your car you have a few things to consider. Mainly you want to decide if you are going to stay emissions legal. If you are going to stay emissions legal then a shorty style header is for you. If meeting emissions requirements isnít necessary then a race header will give better gains.
Here are some of the shorty style headers out on the market for the zetec engine.
Ford racing shorty
Focus central shorty
Shorty headers when used in conjunction with a stock catalytic converters donít produce very large gains. Though a shorty header used in conjunction with a hi flow cat can make very good gains. A shorty header and hi flow cat combo also allow the engine to produce usable low rpm torque, this is good for daily drivers.
Shorty headers do have one con and that is price, a quality shorty will cost close to as much as a race header. Dollar for dollar vs. a race header they arenít as worth it. But if staying emissions legal they are as good as it gets. I have also found that over long term use, an aftermarket shorty can prematurely wear a stock catalytic converter.
Here are some of the race headers your likely to see on the market.
Focus central race header
Focussport race header
Kamikaze race header
For the money, if you plan to make serious power in any form a race header is necessary. Also they cannot be beaten when it comes to price. Average race headers go for between $ 325 - 375
Race headers require removal of the catalytic converter. Many folks cannot remove their cat for emissions reasons. This makes a race header impossible to use.
These are not all of the exhaust headers and race headers available, but simply a selection of the more common ones.
