- My Toyota is already 12 years old, and I’ve been noticing lately that it’s getting noisier than usual. I think the noise has something to do with a bad muffler. How can I tell if the muffler is already worn out?
Excessive noise can be traced to a number of exhaust system glitches such as cracks and holes in manifolds or pipes, blown-up gaskets, or a bad muffler, as you suspected. Rusts on the muffler or a small puncture or hole will turn the exhaust sound a bit louder. There could also be some thumping or clunking noise, which indicates a broken part in the system. The rattling in the muffler is probably caused by broken or loose baffles. Aside from rust and holes, you also need to check for thick, billow smoke from the pipes or water dripping from the muffler. If the engine temperature quickly rises to the point of overheating, then this could mean that you have an exhaust system problem.
- Can I clean the insides of the muffler? They say that this isn’t advisable and that this can be dangerous. Is there any truth to this claim? I just want to remove the accumulated dirt inside.
You’re only supposed to clean the exterior of the muffler. You don’t want the insides of the muffler to get rusty and corroded as you clean it, exposing it to rust and other elements. Cleaning the inner parts of the muffler may only shorten its life.
- What’s the best way to clean a Toyota muffler? What’s a good cleaning solution to use?
Remove surface dirt and soot using a dry rag or some paper towels. A mixture of 1 teaspoon dishwashing soap and a quart of warm water will be a good cleaning solution, especially for wiping out grease and removing stains on the muffler.
- Is it safe to polish a muffler? The one I got on my old Toyota SUV already looks muddy and even dingy. I just want to bring back its old shine.
You can use some polish on the muffler. However, you have to choose the right one according to the muffler finish or material. For instance, you may have to choose a chrome polish or look for a polish that’s safe or designed for aluminum. The polish should be applied using a dry, soft rag. A good alternative to the metal polish is toothpaste applied using a toothbrush. This can be used to restore the shiny metal surface. When polishing the muffler, make sure that it’s completely dry and clean.
- I found some small holes around the muffler, and I’m looking for a quick fix for this until I’m able to buy a new muffler and have this replaced completely. What would be my options for fixing the muffler leak?
Some muffler repair kits may include some kind of patch or epoxy. Before applying the epoxy or using the patch, the muffler should be sanded to get rid of rust and dirt first. The patch may be glued or welded on the punctured muffler. Muffler tape is also used to cover up the holes temporarily.
- I was shopping for some tape that I can use to cover up the muffler holes, but then my brother-in-law told me not to waste money on this repair solution because it simply won’t work. Is muffler tape really a bad idea?
The muffler tape doesn’t always work for all. Some who have used the muffler tape have complained that the tape eventually fell off. It didn’t bond to the pipe even if they have sanded down the surface and cleaned it thoroughly. You should consider this a temporary fix. If you want a more permanent solution, it would be best if you replace the muffler altogether, especially if there’s rust all over and there’s a lot of holes.
- How does a muffler bandage work?
A muffler bandage is a strip of cloth that’s chemically enhanced. It can be made out of fiberglass or silicone. The bandage is used to cover up the damaged area on the muffler. It’s wrapped around and pressed into place. The heat from the engine will harden the bandage and eventually seal it.
Choosing the Right Toyota Muffler
When shopping for a new muffler, one of the first things that come to mind is the exhaust sound. From a throaty growl to a soft purr or a mighty roar, you can give the vehicle the best sound with the right type of muffler. You can make it sound better to the tune of high performance or simply let it run quietly. Other than the sound, the Toyota muffler you will get should allow the vehicle to exhale gases easily without restricting flow. In search for a brand-new muffler, you should consider the design and specs to find the perfect match to the vehicle.
Consider the specs-inlets, diameters, and other details.
First things first-you have to consider what kind of system the vehicle is equipped with, whether it's single or dual. This will tell you how many inlets is needed on the new muffler. Another crucial detail is the size and length. You must know the exhaust pipe diameter to find a suitable replacement or upgrade that will fit. The muffler should come with the right outside dimensions for proper clearance. With the right size of muffler, you won't be dealing with installation problems clamping issues. It will easily fit into the vehicle's exhaust system links the undercarriage.
Make your choice between chambered, turbo, and straight-through.
Each type has its own set of benefits and features. To choose the right muffler, let us give you an idea about what keeps one different or better than the other. Chambered mufflers are great options for street machines and muscle cars. This is because they're designed to minimize exhaust noise, yet they produce a throaty performance note. The exhaust tone and noise reduction ability of chambered mufflers depends on the size, number of chambers, and other features such as sound-deadening baffles or inserts within the chambers.
While chambered mufflers offer minimized exhaust noise and a throaty sound, the straight-through types are known for maximizing flow. Maximum flow paves the way for increased horsepower. This type of muffler is built with a straight, perforated pipe that's packed in a sound-absorbing material. If the chambered type is best for street machines and muscle cars, this is ideal for racing. This is because this design makes it easier for the vehicle to exhale as it lets the exhaust gas flow through the pipe with less restrictions. This doesn't have the same sound reduction capability of chambered mufflers. Since it's more compact, it's a preferred choice for street rodders and custom car builders.
Turbo mufflers typically consist of a set of perforated tubes. These direct the exhaust gasses through the muffler. The S-shaped pattern lets the gasses flow through more tubing, resulting in increased noise reduction capability. Some turbo-style mufflers even use a sound-deadening material wrapped around the tubes. The design, however, is more restrictive than others. This is recommended for street applications.
Know the better option between aluminized and stainless steel mufflers.
The muffler should be able to handle high pressure exhaust gasses. As part of the vehicle's undercarriage, it should be able to absorb impact from road debris. It should also have high corrosion resistance to prevent wear and extending damage to other links of the exhaust. Typically, several layers are used for the body: outer shell, inner case, and an insulated layer in between. The muffler body can be manufactured out of aluminized steel, which is less expensive and stainless steel that's a bit more durable.
