- I replaced the exhaust headers on my Ford. How much power will I expect to get compared to my previous headers?
You can never tell the specific amount of power or torque that you'll be getting, but you can expect a release of about 5 to 25 horsepower along with visible rear-wheel torque boost. On the other hand, getting a replacement for your existing exhaust headers doesn't really translate to better quality and improved engine performance, unless you upgrade to headers that have higher specs.
- Are all exhaust headers street-legal?
Usually, exhaust headers are legal in all 50 states. However, there are also headers that are designed only for racing or off-road vehicles. Therefore, they are exempted from any smog inspection, making them illegal to streets. That's why it is important that you are extra careful when choosing your replacement Ford exhaust headers. Double-check with your dealer if the parts are legal in your state.
- Is it normal when Ford headers discolor? If yes, will it affect the performance of my engine?
Yes, headers will eventually discolor over time, but if you own ceramic coated headers, they are more elastic and more likely to last. However, if your headers are made from stainless steel, although they are also durable, they will eventually decolorize after a couple of years. Nickel and chrome headers will also change color, especially if they are often used for racing. High-temperature painted headers are also more likely to last, but the color will fade eventually part by part. Nevertheless, discoloration will not affect your engine's performance. Their appearance will not keep your engine from its best performance.
- What advantages can I get if I use ceramic-coated exhaust Ford headers instead of the stainless steel type?
Ceramic-coated exhaust headers work best when it comes to preventing heat damage. The ceramic coating does not only protect the headers from burning out and discoloration, but it also isolates the header's piping, keeping the temperature in your engine compartment down. This results in the improvement of your vehicle's efficiency. Compared to stainless steel headers, this type may be durable but not enough to last long.
- Mild steel or stainless steel exhaust headers: which will work best for my Ford?
Most exhaust headers are made of stainless steel, but these two types of steel are not entirely different. They vary, however, when it comes to price. Mild steel exhaust headers may be cheaper, but comparing their level of durability to stainless steel, they will not win. Stainless steel exhaust headers can cope with extreme heat over a long period of time and won't rust. Stainless steel material is a great choice especially if you are looking for thermal protection. Expect smooth, restriction-free flow on your exhaust system because of its rust-free surface for a long time.
Featuring high-quality .049 mild steel tubing, precision engineering through mandrel bending technology, and leak-tested tubes, Flowtech headers guarantee unrestricted exhaust performance and maximum fuel efficiency. Mandrel-bent tubing allows for a smoother flow of exhaust gases. These headers also employ an exclusive mandrel-formed Power Plenum collector that eliminates tight, restrictive bends and significantly lowers back pressure. The 3-inch collector size and the 1.5-inch tube size ensure a high-flow, high-performance exhaust system. Apart from leak-tested tubing, these headers are also equipped with leak-tested O-ring seals on each port to ensure a precise fit. For a much easier and faster installation process, these headers also come with all the necessary hardware for mounting such as mounting bolts and premium gaskets. With an electrostatically-applied, high-temperature satin black paint finish, these headers can withstand extreme heat and corrosion. Sold as a set of two, these full-length, eight-cylinder headers come with the manufacturer's 90-day warranty,
For lowered or raised pickup trucks and tow vehicles, Gibson Performance headers are the perfect match. With about 10 to 20 gains in horsepower and 10 to 30 lbs. gained in torque especially at low to middle rpm speeds, these dyno-tuned headers deliver a noticeable boost to various vehicles down to each specific model year. Made from heavy-duty, mandrel-bent 409L stainless steel, these headers ensure that the exhaust system enjoys a non-restricted flow. With port flanges that are cut to precision by laser technology, the headers also have maximum protection against distortion and leaking. Installing these headers is also a breeze because of the bolt-on style that easily connects to OE exhaust system components and the complete set of hardware, air injection, and oxygen sensor fittings that come with the headers. Apart from improving the engine performance, the shorty-style construction of these headers also generates a better, deeper, and throatier sound. These performance headers are sold in pairs and come with a lifetime warranty.
Manufactured from an 18-gauge (or a thicker 16 or 14-gauge), mandrel-bent steel tubes and precision-cut to ensure equal length, Hedman headers offer great durability combined with a boost in power by maintaining equal exhaust gas temperatures or EGT. Great for both street and track applications, these full-length, six-cylinder headers also improve exhaust flow and fuel economy. These headers come with a factory black paint that protects the headers from pre-installation damage to ensure that the headers are in perfect condition from manufacturing to installation. These headers require very little adjustment during installation and can be painted with a thermal coating for maximum heat resistance and longer lifespan. Sold as a set of two, these headers come with a lifetime Hedman limited warranty.
