MUFFLER REPAIR How do I know if I need to replace a muffler?
One of the main sources of small engine noise is the hot gases that are forced out of the cylinder during each exhaust stroke.
A muffler does a good job of reducing exhaust noise. But after a season or two, exhaust gases leave a layer of soot in the muffler that creates additional resistance to gases exiting the cylinder.
When hard soot accumulates, when the exhaust emits excessive noise or when cracks or holes appear, don’t try to repair the muffler.
Once a muffler shows signs of deterioration, replace it.
How Your Muffler Works
How do mufflers affect your cars efficiency? We quickly notice when a muffler is not doing its job.
Even small cracks or holes in the muffler can result in a dramatic increase in engine noise.
Do performances exhaust systems and mufflers really work?
I have been asked this question thousands of times ever since I started my career as an auto mechanic. However, I still find it difficult to answer this tricky question.
There are a number of things which has a great impact on the efficiency of exhaust systems and mufflers, especially the exhaust parts.
It is true that exhaust system and muffler manufacturers make a lot of claims about their products. But the claims alone can’t resolve the confusion and eliminate the doubt about them.
Their effectiveness can vary to a great extent depending on the model of the car, its condition as well as its maintenance. However, I will still try to make you clear about how these mufflers and exhaust systems actually work and how they can bring a visible difference in the performance of a car.
The Exhaust parts, especially the performance mufflers together with exhaust parts, do improve the efficiency of a car.
You should keep in mind that they do not add any extra power in your car when you install them. Rather those performance mufflers actually improve the efficiency of your car. Most of the standard cars have a restrictive exhaust system to keep the cars quiet and they also cost less.
These restrictive exhausts and mufflers actually hold down your car and push down its efficiency. But when you change the standard exhaust with a performance muffler and exhaust, your car engine will exhale more freely. As a result, your car will get some power which was initially trapped within itself.
