The federal gasoline guidelines require every dodge ram pick-up truck have an exhaust system capable of expelling toxic combustion fumes. California emissions make it mandatory that dodge ram vehicles contain all of the above exhaust system components as well as catalytic converters attached to the exhaust pipe. The exhaust system must be arranged appropriately to prevent exhaust leakage and contact to the supporting fame under the body of the truck.
Strict clearance tolerance between any exhaust system component and the body or undercarriage be a minimum of If an exhaust system makes contact with any frame structure it will increase the volume to an objectionable noise level.
If you plan to remove the exhaust system with a blowtorch, do not set fire to nearby fuel lines. Use these instructions if you plan detach or take off any part of the exhaust system. A catalytic converter is a antipollution device on a dodge ram exhaust system that utilizes a catalyst for converting harmful pollutant gasses into less dangerous ones. The catalytic converters on the dodge ram are made of stainless steel and should last the life of the full-size pickup truck.
The converters are termed crossover pipe or Y-pipe. Excessive heat will not cause a converter to fail but it can result in bulging or distortion. Catalytic converter malfunctions happen when unburned fuel enters it and lead to overheating. Replace the converter if it is heat-damaged and correct the issue that caused impairment. Carefully inspect other exhaust system components for heat damage. Note: The clamp that fastens the exhaust manifold and catalytic converter together should not be reused, replace it with a new part.
A heat shield is a steel or foil sheet used as an outer covering or coating for protection from excessive heat. The dodge ram utilizes both molded foil and stamped steel heat shields. The shields are attached underneath the vehicle in areas around the exhaust system. Never operate the vehicle without heat shields properly installed. The heat generated from the exhaust can or will cause damage to other components.
Slide the shield out around ………. Muffler A muffler is device fixed to the exhaust of motor vehicle to silence or reduce engine noise.
A typical dodge ram muffler will last 40, to 80, miles depending on climate conditions i. Muffler: 1 Insulator. Take off clamps and nuts. Remove the muffler. Installation Assemble exhaust system muffler and clamps loosely on the vehicle so as to allow for proper alignment before torquing the clamp nuts.
Fasten the muffler to the insulator hangers, also termed muffler hanger or exhaust hanger. The insulators are made of rubber to absorb vibrations and dampen sound. Torque the clamp nuts to Lower the vehicle. Start the engine and examine the exhaust system to ensure there are no leaks.
Check exhaust system to make sure it is not making contact with frame or body panels. Emission regulations require a minimum clearance of Tailpipe Remove Raise and support the pickup truck on a flat level surface. Use heat valve lubricant to soak the clamp nuts. Allow lubricant to penetrate the clamp nuts for 5 minutes. The lubricant will help loosen nuts covered in rust. Warning Close. Confirm Action Are you sure you wish to do this?

If you somehow miss that symptom, you may also notice a big jump in how much fuel your car uses or a backfire when you accelerate.
Fortunately, you can remove the catalytic converter with a few small steps. Raise and support the entire truck on jack stands. Disconnect the negative cable on the battery as a precaution. Disengage the electrical connectors to the oxygen sensors. There are two oxygen sensors attached to each catalytic convertera pre-converter sensor located near the front end of the converter and a post-converter sensor near the end.
Use a small ratchet wrench to remove the flange bolts connecting the catalytic converter to the exhaust pipe. Separate the pipe from the converter, and support the pipe. You can use the truck's floor jack, but place a board on top of the jack to keep it from damaging the pipe. Remove the bolts that attach the converter's header pipe to the exhaust manifold. The studs and nuts here often are rusty, so apply penetrating oil to them for easier removal.
Take off the catalytic converter and its pipe assembly. Repeat for the other converter if needed. Clean away any carbon deposits built up on the mounting flanges with brake cleaner or the penetrating oil. Discard the gaskets; use new gaskets on the flanges when the new catalytic converter is installed. How to Remove the Catalytic Converter in a Blazer.
