Your car's stock exhaust system is designed to restrict the engine's horsepower. The exhaust system also does a good job keeping exhaust noise down. You see, if you were to run an engine without an exhaust manifold on its exhaust ports, it'll sound like a ship entering a port. It's that loud.The exhaust system installed in the factory has two basic parts that reduce noise - the center muffler (a.k.a. 'resonator') and the rear muffler (a.k.a. 'silencer'). The resonator is in charge of toning down the exhaust noise, turning it into a melodic, low-pitched buzz. The silencer does as its name suggests - it silences the exhaust buzz.A car without a silencer is still bearable, but take away the resonator and you're in for a world of complaints from both your neighbors and passengers. You're probably going to tick off a lot of highway cops as well.If you want to keep the peace, make sure your center muffler is in good condition. Once your exhaust starts getting louder, grab replacement components here at Carparts.

  • Steps in Installing a New Center Muffler 11 January 2013

    A bad center muffler is quite easy to detect. Since it is the one responsible for lessening the noise the engine produces, you will hear low, booming or hissing sounds in your exhaust system if it is failing. More so, a great deal of soot or rust will develop on a bad center muffler. If you notice any of these signs, you need to buy a new one. You can even install it at the comforts of your home. Following are the simple steps.

    Required skill level: Expert

    Needed tools and materials

    1. Jack lifts
    2. Jack stands
    3. Marker
    4. Muffler pipe bands
    5. New center muffler
    6. Ratchet set
    7. Reciprocating saw
    8. Socket wrench
    9. Torque wrench

    Accessing the muffler

    With the use of jack lifts and stands, raise and secure the rear part of the vehicle. Work under the vehicle and locate the muffler. Mark both sides of the muffler wherein it is connected to the exhaust pipe for three inches. Measure the distance between the two marks to know how long you need to cut the new muffler for it to fit.

    Removing the old center muffler

    With the use of the reciprocating saw with the correct blades, cut the old muffler out of the exhaust system. Vertically align the blades from the floor along the process. To ensure that the new center muffler will fit well, cut the old exhaust pipe with slow up and down motions.

    Dismantling the tailpipe

    Once the center muffler is removed, also take out the tailpipe from the car body. The tailpipe might be attached with bolts and bands. Remove these fasteners using the correct tools. Once removed, set the tailpipe aside if you are going to reinstall it with the new center muffler.

    Installing the new center muffler

    Slide the new muffler into the existing exhaust pipe. Have a muffler band on the end of the muffler connecting to the exhaust pipe. Once the muffler band is positioned well between the exhaust pipe and the new muffler, tighten its nuts with the use of torque wrench. Use the same torque on all the nuts to make sure there is no damage.

    Mounting the tailpipe

    Once the muffler is installed, mount the tailpipe to the other side of the muffler. Undergo the same procedure as when installing the muffler.
