This is a sunny Saturday afternoon, the sun is shining, and you have decided that today is the perfect day to take a "hot rod" drive. You climb behind the steering wheel, and when the engine ignites, you have a big smile on your face. Things are impermanent. Unfortunately, after only a few miles of driving, you will remember why your pride and joy are not as much as you hoped-the inside of the car will become very hot. Have you ever wondered why?
Of course, air conditioning will help, but this is not what we are going to discuss. What many enthusiasts have to deal with when driving a car is the engine heat radiating to the area where they plant their buttocks. In other words, the heat under the hood will radiate into the car and affect the comfort of your ride. The people at Design Engineering Inc. (DEI) are well aware of this situation and can help.
If you choose to lower the temperature under the hood, there is a way to provide good results, but it is not without controversy-head wrap. Talking about head packaging among a group of Autobots, you will definitely start a heated (pun intended) discussion.
To ensure that your title and packaging are properly protected from elements, proper preparation is key. HT silicone coating can provide long-lasting protection for any high temperature surface up to 1,500 degrees. DEI recommends using this coating with exhaust hoods because it seals the material and provides long-lasting protection against oil, dust, and road dirt.
Usually, I am full of opinions on a given situation or part, but this time, I want to contact the person who actually made the title wrapper to see what they can give us. But before we listen to the opinions of professionals, let us figure out a few things.
The biggest topic of discussion revolved around the headline-wrapped report that caused the headline to rust. According to Eric Baun of DEI, “Any mild steel exhaust pipe will rust over time-with or without an exhaust wrap. The cloth will not absorb moisture from the air, but if you are in wet conditions Riding or driving without letting the wrap dry out will cause accelerated oxidation. If your package gets wet, please let the engine run long enough to dry the package."
DEI says that before packing the header, you must ensure that the surface of the tube is clean and free of rust.
Although the headings of the packaging look cool-again, in my opinion-heading packaging is not just for appearance, they do have a function when properly installed. "Wrapped ducts help control exhaust temperature and reduce radiant heat under the hood," Eric said. "Hot exhaust gas flows faster, improving exhaust gas removal, thereby increasing power. Limiting radiant heat in the engine compartment can also reduce the ambient temperature of electronic equipment, air intakes and firewalls. Cooler components have a longer life and more effective Good. The performance of the cooler drive is also better."
DEI offers three types of materials: fiberglass, titanium and EXO. Each has its benefits, and budget is usually the main consideration. DEI's glass fiber is the cheapest, up to 1,200 degrees. Titanium wraps can withstand temperatures up to 1,800 degrees. Design Engineering's EXO packaging is designed for extreme environments. According to DEI, traditional exhaust hoods cannot withstand the extreme use of off-road, dirt road, desert and other forms of driving experience exposed to water and dirt. Although designed for off-road use, it is a good choice for street and racing enthusiasts who never leave asphalt or concrete.
The EXO series adopts a double-layer design and is made of high-temperature resistant glass fiber, and is covered with a grade 304 stainless steel exoskeleton. We are told that this unique structure maintains excellent thermal protection and provides excellent wear and impact protection.
You can find different styles of title wrapping, and finding the most suitable application for you is as easy as calling DEI.
Eric said there are a few things to consider before installing the header wrapper on your header. "We recommend cleaning the header as much as possible to remove any surface rust," Baun said. We also recommend HT Silicone Spray primer before packaging to protect them as much as possible. This should be done regardless of whether they are a new or old set of headings. "
Frequently asked questions about header wrapping Why should I wrap my header, pipe or tubular manifold? When controlling exhaust temperature and reducing radiant heat under the hood, wrapping any type of exhaust duct is a crucial step. Keeping the exhaust gas temperature in the exhaust system higher helps reduce density and increase exhaust gas flow. This improves exhaust purification, thereby increasing power. In addition, limiting the radiant heat in the engine compartment can reduce the temperature by as much as 50%. This reduces heat absorption from electronic equipment, air intakes and firewalls, and keeps instrument panel components and cabin temperatures at an absolute minimum. How is the exhaust hood made? DEI fiberglass exhaust hood is mainly made of fiberglass material and has been treated with a proprietary coating developed by DEI. Compared with other brands, this combination helps to increase the thermal resistance of the packaging. The DEI Titanium exhaust hood uses basalt as the main material. Will wrapping my pipes make them rust? Any mild steel exhaust pipe will rust over time-with or without an exhaust package. If you wrap any type of pipe, we recommend using our HT silicone coating to seal and protect the wrap, even the pipe you wrap. In addition to adding color to the wrap, HT Silicone Coating extends the life of the wrap by locking the fibers together. You can wrap most types of metal. Will DEI Exhaust Wrap treat my exhaust gas? Yes. Factory pipe manifolds and other exhaust system components can be wrapped to help control heat, including pipes for intercoolers and turbine downcomers. What can keep my exhaust pipe in place? DEI stainless steel locking straps are designed to hold your exhaust package firmly in place and have a perfect appearance. Our locking lacing tools make installing them quick and easy. Stainless steel hose clamps or lock wires can also be used. After wrapping the heads, check them regularly for wear that may cause the packaging to fall apart or loosen. This wear may come from the steering linkage or other moving parts in the engine compartment. If this happens, corrosion will occur faster. According to Eric, "After the system is packaged, there should be almost no maintenance. However, if the package has faded, you can also use HT silicone spray to restore the color of the package. In addition, the header that handles the package after the thermal cycle should be kept in at the lowest limit."

A question often asked by later model enthusiasts is "Can I wrap my catalytic converter or the flexible tube connected to it"? According to DEI, you should never pack these parts. "Wrapping these components will absorb too much heat and cause premature failure of the CAT internal components," Eric said. "For these situations, we recommend using ducts or CAT specific shields to block radiant heat while still allowing airflow through the CAT or flexible duct section."
Whether you decide to wrap or not to wrap your headline should not be decided only by reading Internet forums. Take a moment to contact someone at Design Engineering Inc. and ask questions. Tell the technical representative what your plan is, why you think you might need to bandage your head, and the environment your car is in. Having reliable information is the best way to decide what is best for you.
