Headers are an important component of any vehicle and the GMC Sierra is no exception. When installed correctly, they can provide a number of performance improvements. In this section, we will look at the different types of headers available for the GMC Sierra and examine the features they have to offer.
Long Tube Headers: Long tube headers are the longest type of header you can get for your GMC Sierra. They offer increased ultimate power potential by providing more surface area for scavenging gases from the engine cylinders, allowing more efficient exhaust flow. Long tube headers usually require a form of exhaust fabrication to be used in combination with them, such as an X-pipe or an H-pipe for optimal performance, which may add costs to your build.
Shorty Headers: Shorty headers are designed with shorter primary tubes than their long tube counterparts and do not require further fabrication for use with an exhaust system. This makes them a popular choice among those looking for short-term power gains and better street performance without additional costs associated with long tube headers. However, keep in mind that because of their smaller design, scavenging performance may not reach that of long tube headers in certain applications.
Tri-Y Headers: Tri-Y headers combine some aspects from both shorty and long tube designs – they feature shorter primary tubes than traditional long tubes but also have 2 additional separate secondary tubes which create scavenging effects similar to those found on long tubes while eliminating some excessive noise typically associated with these larger systems. As such, these may be the most viable option if you’re looking for an improvement over stock that isn’t too extreme.

Coating
When selecting parts for a GMC Sierra, an important factor to consider is the coating that has been applied to the parts. Parts can be electrostatically coated, powder-coated or sprayed depending on the application and manufacturer’s specifications.
Electrostatic coating is a process that utilizes electrical currents to electroplate metal surfaces with either plastics or epoxies. This type of plating is often found on sheet metal like frame components where it can provide additional durability and rust protection.
Powder-coating is a dry finishing process in which finely milled particles of pigment are baked onto the part surface with heat to create a protective layer that can take a beating from trail use. Body panels are often powder-coated for increased cosmetic appeal and corrosion resistance.
Spraying is a basic form of paint application and involves applying various types of quick drying enamel or lacquer paints to surface areas with an airbrush or compressed airgun system. Spraying provides superior cosmetic enhancement and corrosion protection when used in combination with primer coatings but fades over time due to exposure unless regularly maintained with waxes, clear coats, etc.
Diameter
The diameter of the GMC Sierra’s wheels range from 15 to 22 inches, depending on the model year, trim level and other features included in the package. A higher diameter wheel will generally improve road performance, while a lower diameter wheel may offer better off-road traction.
Shorter sidewall tires and larger wheel diameters also allow for improved corner grip, maneuverability and acceleration. Bigger wheels can improve acceleration and brake response by reducing the rotational mass of the tire. Additionally, many performance wheels are designed for lightweight alloy metals that can further reduce rotational inertia.
Larger wheel diameters generally require larger brakes for optimal braking performance. Even increasing your wheel size by just a few inches can make a big difference in your braking dynamics due to the extra weight from larger wheels.
Ultimately, selecting a tire and/or wheel size for your GMC Sierra should be based on individual preferences as well as purchasing budget – along with consideration for environmental impacts including road noise levels caused by certain tire size combinations – as no one size fits all when it comes to automotive customization.
