Among the components that play a significant role in your vehicle's exhaust system is the header pipe. Also known as the exhaust manifold, the header pipe is responsible for channeling the engine's exhaust from the cylinders to the exhaust pipe. The header pipe helps increase the engine's volumetric efficiency by preventing backpressure. The engine's volumetric efficiency refers to the engine's ability to move fuel and air into and out of the cylinders. When exhaust gases re-enter your vehicle's engine, the engine is forced to work twice as hard in pushing these gases out. By preventing backpressure, the header pipe guarantees power gains and smooth exhaust flow for your vehicle. So keep the header pipe in tiptop condition. Replace it when it becomes corroded or cracked due to heat and pressure. Carparts can provide your vehicle's next header pipe at a pocket-friendly price.

Make Your Engine Exhale Better with a Header Pipe
A car engine ignites a process called combustion and uses fuel as its key ingredient. Unfortunately, this intense process happens under your hood, and you don't get to see it. Going back to the combustion process, this will yield exhaust gases after interval explosions. These gases are released by an exhaust header also know as a header pipe connected to the cylinders. Without that heade pipe, the gases will clog the flow, and result to a total engine malfunction. Read on to know the right type of header pipe for your car to increase its performance.
Choosing between plain and stainless steel header pipes
With different types of header pipes out there, checking the type of the material is a good starting point. Here's why:
- Plain steel header pipe
This material is easier on your pocket because it's cheaper, but it wouldn't last that long. If a plain steel header pipe is not properly maintained, it will definitely corrode or rust in time.
- Stainless steel header pipe
A stainless steel header will last longer especially with a ceramic coating. It will give the best look when it turns blue or purple as reaction to extreme heat. There may be other coatings used by manufacturers, but a ceramic coating is assured to withstand high temperatures.
Importance of length to a header pipe
Before talking lengths, check your engine compartment because you can already determine what you'll need just by looking at the space it has. A long tube header pipe will perform better because it can contain more gases, but if it won't fit, a short header pipe also called "shorty" is the best alternative. Though shorter, it's easier to install compared to the long tube.
Other things to consider
Apart from choosing the material used and the length of a header pipe, you can also check the list below to help you narrow down your search:
- You have to determine the number of cylinders in your car's engine. This should be the same with the number of pipes you want to buy.
- Check if your vehicle has to undergo emission compliance. In some states, vehicles that are above 30 years are exempted from testing. If your car is not included, choose a header pipe that can function with a smog equipment. You have to know the restrictions in your local area before buying a header pipe to avoid any run-in with the law.
Installing a Header Pipe Within the Comforts of Your Own Garage
If you want to maximize your vehicle's performance, then start checking under the hood. Can you see the exhaust manifold? That's the first thing you need to remove, and replace it with a header pipe. This installation guide will show you how to do it in just few easy steps.
Difficulty level: Difficult
- Floor jack
- Jack stands
- Socket set
- Wrench set
- New header pipe
Step 1: Park your car on a clean, level surface. Make sure the engine has cooled down before you begin to work.
Step 2: Disconnect the battery's negative terminal and the electrical oxygen sensors.
Step 3: Jack the car until you can work comfortably underneath. Place the jack stands on the car's solid frame, and remove the jack.
Step 4: Remove the bolts from the manifold's exhaust mid-pipe using the ratchet, and remove the entire mid-pipe.
Step 5: Disconnect the spark plug wires and remove the spark plugs that block your access to the manifold. Remove the alternators and all other parts that block your passage to the manifold. Remember their positions so they'll be easier to place back.
Step 6: Use the wrench to unbolt and remove the manifold. It is advisable to remove the manifold from top to bottom, but check first where you can start comfortably.
Step 7: Take the header pipe and check if the hardware is complete. Fit it in the manifold position, and start bolting the pipe.
Step 8: After the pipe is bolted in place, start placing all the parts to their previous position until you finally reattach the mid-pipe to the header pipe.
Step 9: Reconnect the electrical oxygen sensors and the battery. Start the engine and observe the new header pipe.
Step 10: Jack the car once again to dismount your car from the jack stands.
