Some vehicles will have them and some will not. Resonators cancel out a certain range of sound frequencies. Resonators prepare the loud noise coming from your engine for the muffler to silence it.

When a car is designed, a team of acoustic engineers work to make sure that the sounds that come from your vehicle are as pleasant as possible. The problem that these engineers encounter is that the quieter an engine is, the less efficient and powerful it is. They could make a muffler that makes nearly no noise, however it would be so overly restrictive that the vehicle would become ridiculously slow and have a horrible fuel economy.

The resonator is a sort of compromise. Nonetheless, just because you can do so, doesn't mean that you should do it. Personally, using a pipe is one thing that I do not advise. It can be cheaper and more convenient, but the cons may outweigh the pros.

When you take out the exhaust resonator and replace it with a pipe, the back pressure can be affected. It will reduce the efficiency of your car and you might end up consuming more fuel while also hearing a louder noise.

Why is back pressure important? As it has been discussed in the short video clip above, back pressure is provided by the resonator, insuring that the exhaust gases will come out engine at the correct rate. Consequently, this leads to achieving peak performance and saving fuel. Again, this explains why replacement of the resonator may have a smaller or larger impact on your engine. The best reason to replace your exhaust resonator is to optimize the performance of your engine or your car in general.

As noted above, it can create less pressure but at the same time it can be too restrictive. You could achievement more horse power. It is also affects your fuel efficiency. If you want to save money in the long run, consider replacing the exhaust resonator that you currently have with a new one or a pipe. This may help if there's any restriction of air flow from years of soot. If you are wondering about when the exhaust resonator should be replaced, one thing that you should do is to perform a quick visual inspection.

If it is rusted, dented, or damaged in any way, this is obviously the sign that it is seeking a replacement. If you notice that the engine is roaring too loud or if there is too much combustion, these can also be signs. It has been pointed out that a pipe may not be best as a replacement for an exhaust resonator, although some people do use it. That being said, the best replacement for an old exhaust resonator is a new exhaust resonator.
