Do you get headaches when there's too much noise? Some people do. If the noise is just coming from your surrounding, you can easily remedy this by changing locations. However, if the noise is coming from your own car, you really can't escape it unless you get your car fixed as soon as possible. Noise usually happens when the Center Muffler gets busted. As you know, the muffler serves as the car's silencer; hence, the term "muffling" the noise. As the engine's exhaust blows through the muffler, various elements within this tube cancels the noise out so that all that comes out is a soft and pleasant purr. The best option is a replacement if you want to address the problem in just one sitting and be free from worries. In order to replace the Center Muffler, you must first find its exact location. In most models, the main muffler is usually found within the left-hand chassis rail, just below the pillar. Like in all replacement tasks, make sure you do so carefully. A word of caution, though: do the replacement only if you are a seasoned DIYer. If you can't tell one end of your car from the other, then better leave that to the professionals. Remember, finding a high-quality muffler replacement is also important. That part is easy if you look here at Auto Parts Warehouse. Why shop elsewhere when our site can provide you with the quality part you have been looking for at a very reasonable price?

Center Muffler Specs That Buyers Have to Check

Your vehicle may roar too loud if not for the center muffler that cancels out engine noise. Aside from reducing noise, the muffler also minimizes back pressure, which can affect engine efficiency if there’s too much of it. Unfortunately, the muffler may rust or even fall off the vehicle when it hits an object on the road or when it wears out over time. When the muffler is no longer in great shape and is about to collapse, you should get a suitable muffler replacement.

Different muffler materials

The center muffler can be made of any of these materials: stainless steel, aluminized mild steel, or aluminum. Out of all the options, stainless steel mufflers are the most durable as they resist corrosion, while aluminized mild steel mufflers usually last for about 4 years. Aluminum mufflers are lightweight but might get cracked or warped over time. Some mufflers may also be mixed with fiberglass or steel wool for better sound reduction.

Standard vs. performance muffler

Standard mufflers come with the traditional back box design with chambers and cylinders. These mufflers are designed to bounce around pressure waves for cancelling out noise and to minimize engine heat and improve exhaust flow. They pass smog tests and meet most standards. High-performance mufflers, on the other hand, typically come in a straight steel pipe, which may be designed with louvers or perforations. They can enhance vehicle performance but may not reduce sound as effectively as standard mufflers. The various designs of performance mufflers include the bullet, perforated bullet, louvered bullet, chambered bullet, full case, cherry bomb, multiple baffle, and turbo mufflers. Standard mufflers are best for everyday driving while performance mufflers are best for car owners concerned with speed and vehicle performance in different conditions.


Universal mufflers fit only some vehicle types. They don’t fit all vehicle models. Some of them might require modifications such as welding, cutting, and pipe bending. Look for a center muffler that fits your vehicle’s exhaust system. You may consult the vehicle manual for important details such as the size (length, width, and height), configuration, location, attachment, and other particulars in the design. Some mufflers maintain the stock sound level and factory finish; others provide better options. Direct-fit center mufflers can usually be clamped on with no modifications needed. Make sure they’re precision engineered and manufactured from top-grade materials for reliable structural integrity and good exhaust performance.

Sure Steps in Replacing a Center Muffler

Your muffler may no longer be up to snuff. It may be plugged with oil particles or rusted. It may be punctured with holes or may have collapsed when an object hit it badly. For sure, the damaged muffler will affect the sounds your vehicle makes and how it runs. If it’s time to replace the center muffler, here’s how:

Difficulty level: Moderate

Things you’ll need:

  • Sockets with a ratchet wrench
  • Hacksaw or electric reciprocating saw (or any similar cutoff tool)
  • Ball peen hammer
  • Wrenches
  • Jack and jack stands
  • Wheel blocks
  • Muffler sealant
  • Exhaust clamps
  • Penetrating oil

Step 1: Park the vehicle on a level surface. Set the transmission to park and activate the emergency brakes. Place wheel blocks under the rear wheels before raising the vehicle using a jack and supporting the frame with jack stands on each side.

Step 2: Apply penetrating oil on the nuts (and clamps for a clamped-on center muffler). Let this sit for a while before using deep wall sockets to loosen the muffler clamps.

Step 3: Free the muffler from the pipe on the rear and front. You may have to use a hack saw or electric cut-off tool for separating the pipe.

Step 4: Once the muffler is separated from the pipe, detach it from the hangers that secure it in place.

Step 5: Install the new center muffler. Check the instruction manual that came with the muffler. Installation is normally the reverse of muffler removal.

Step 6: Keep the ends of the pipe smooth. Its rear portion must be split to expand, and the new muffler’s rear end must slide into the pipe.

Step 7: Place the muffler onto the hangers and make sure it mounts properly.

Step 8: Coat the pipe at the front and rear with muffler sealant.

Step 9: Place new muffler clamps on pipe ends. The muffler must slip onto the ends. Once in place, set the clamps over the connections between the muffler and pipe. Use deep wall sockets and a ratchet wrench for tightening the clamps. Then, tighten the nuts. They must run onto the clamps on both ends.

Step 10: Take out the jack stands before lowering the vehicle with the jack. Remove the wheel blocks.

Step 11: Test the new muffler. Drive the car to see if the exhaust is making unusual noise and if adjustments should be done on the connection.
