Jeep Exhaust System Articles

The human body has an excretory system to dispose the toxic materials that can pollute the different parts making up the entire systems. The same purpose is done by Jeep exhaust system. Exhaust systems are made up of components that assist the movement of waste materials from the car's engine to the tailpipe for disposal in the environment. Jeep models which include Wrangler, Liberty and Grand Cherokee are equipped with the newest high-performance dual exhaust system or cat-back exhaust system.

Dual Exhaust systems are made up of piping and one or two mufflers and tailpipes. It provides better breathing capacity by providing easier flow of materials and thus reduces pressure, increases torque and improves the performance of the vehicle. With much better breathing capacity, more exhaust gas are disposed with more space left for an extra air and fuel mixture. Each part making up the jeep's exhaust system plays a vital role in carrying out the function of the whole system. The tailpipe, muffler, catalytic converter, EGR and PCV valves, air pump, exhaust manifold, header, exhaust pipe gaskets and exhaust pipe hangers are just a few of the components included in the system.

Tailpipes or exhaust tips are the visible part of the exhaust system usually located at the rear area under the car's body. It is where the car's exhaust is disposed out into the atmosphere. Mufflers are used to muffle or tone down the noise produced by the exhaust gas due to extremely high pressure. It is made up of tubes, metal holes and plates to diffuse the impact of sound as it go out of the tail pipe. Two types of muffler design are commonly used. The first type pushes the gas into a straight perforated pipe covered with metal or fiberglass to reduce backpressure and tone down the sound. The second type has several baffled chambers to accomplish the same purpose. Catalytic converters are used to purify the harmful gases that negatively affect the environment as it goes out of the jeep's system. The pollutants produced from the imperfect combustion of air and fuel mixture are converted from harmful to harmless through a chemical reaction that occurs as the gas passes into the car's catalytic converter.

The EGR valve or Exhaust Gas Recirculation is utilized to send back or re-circulate the exhaust gas, specifically the harmful Nitrous oxides, into the cylinders to lower combustion temperature and thereby decreasing the amount of Nitrous oxides produced. This pollutant is the major component of smog. The PCV valve on the other hand or Positive Crankcase Ventilation system functions as the old "dump tube" which removes combustion gases and vapors that may get stuck in the piston rings and crankcase that can cause rust, corrosion and bogs.

Closer Look at Jeep Exhaust System

The Jeep exhaust system is designed to carry the emissions produced by the combustion process away from the engine in a smooth and efficient flow, helping to maintain the performance and power of the engine. The engine produces a number of waste products during its operation. Among these are several chemicals that are harmful to the environment and humans, contributing to smog and acid rain, and intense waves of sound, generated by engine combustion. These sound waves and chemical emissions would produce unacceptable levels of air and noise pollution if allowed to pass freely from the vehicle. The Jeep exhaust system processes these pollutants as they pass through its chain of components, reducing the concentration of hazardous chemicals and quieting the noise of combustion. The hot exhaust gasses and the sound waves from engine combustion are collected by the Jeep exhaust manifold as they are expelled by the exhaust cylinders of the engine, then are directed through the exhaust pipes to the catalytic converter. The catalytic converter is the component that reduces the toxic chemicals released by the vehicle, using a ceramic honeycomb style structure that is coated with several catalyst metals to create a chemical reaction with their molecules, causing some to burn and others to become trapped. Once the vehicle emissions have emerged from the catalytic converter with the chemical content significantly reduced, they are directed through the system to the muffler, which is in charge of controlling the noise. We carry a selection of quality Jeep exhaust replacement parts in our online catalog, all at very reasonable prices.

Jeep Exhaust System Repair: How to Fix an Exhaust Leak

The exhaust system sees to it that combustion gases have nowhere else to go but out into the tailpipe. They also keep the noise down through the muffler and converts the exhaust gases into less toxic substances for cleaner, safer emissions. If there's a leak in your Jeep exhaust system, you will notice some changes for sure. The exhaust leak near the manifold can lead to lower MPGs or poor fuel efficiency. The sensor that's supposed to accurately measure the amount of unburned and outgoing oxygen can send incorrect signals because of the leak. As a result, more drops of fuel may be burned than necessary. The leaks will also make the gas pedal vibrate as you drive and accelerate since the fumes are escaping. The vibrations can be felt not only on the gas pedal but also on the steering wheel and even the floor boards. These can only get worse as the leaks get bigger. You'll also notice a noisier engine, especially when accelerating. Here are some things you can do to fix the exhaust leak:

Difficulty level: Moderate

Things you'll need:

  • Safety glasses
  • Flashlight
  • Flathead screwdriver or pry bar
  • Welder
  • Muffler tape
  • Exhaust clamps
  • Joint pliers

Note: You have to trace the source of the leak to find out how this can be sealed. While some exhausts systems are clamped, others are welded at connection points. The design and condition of the exhaust system will tell you how the leaks can be sealed and if parts must be replaced.

Step 1: Start with checking the exhaust manifold. Check for cracks. As you look around under the hood, see where the exhaust manifold meets the engine block. See if there's soot or burned paint. Also watch out for any hissing or popping. You may have to replace the manifold gasket. If the manifold, however, is cracked, you have to replace the manifold.

Step 2:Look for that part where the manifold/header meets the exhaust pipe. There, you'll find a gasket that seals at the joint. Check for soot and for hot gases. You may also hear some noise around the joint. If a blown gasket is the cause of the leak, replace it.

Step 3:Inspect the exhaust pipe underneath the vehicle. Check the front first and then get through the rear bumper. Look for rusty parts. You can use the screwdriver for scraping to see if rust is on the surface only or has gone through the pipe. For small holes, use a muffler tape to wrap around the pipe and seal the leak. For larger rusty parts, see if the parts are already weak. With joint pliers, squish the pipe carefully. If it bends, replace that portion.

Step 4:Examine the joints where the pipe meets the catalytic converter and muffler. Watch out for noises and hot gases. See if the clamps are tight. If they're not, replace them if needed. Also inspect the welds, if the joints are welded. If they're weak or rusty, they have to be re-welded.

Step 5:Check the exhaust system components such as the catalytic converter or muffler. If they have holes or cracks, it would be best to just replace them than attempt to repair them.

Step 6:See if the hangers, along with the clamps, are tight. They must be inspected after new components are installed.

You must wear safety glasses since rust and dust from exhaust pipes can get into your eyes. When checking for exhaust leaks, do this in a well-ventilated area to be safe.
