In fact, if you experience a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will generate a much higher noise than during normal use. In addition, it is also highly plausible that loud noise on your Lexus ES is connected to a wheel bearing, which is one of the most common origins of these types of symptoms. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

The loud noise comes from the wheels of my Lexus ES
As we have seen before, loud noise from the wheels of your Lexus ES may be linked to two main disorders. If it is one of your tired bearings, it will tend to make a thumping noise that intensifies when it is under stress (spins faster and faster). So remember to examine by driving “fast” (neutral gear on and window open to hear only the noise of the wheels) that the noise is located here, if this is the case replace it or them straight away. If it is a deformed tire, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Lexus ES that is the matter, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both circumstances, you will have to go to your auto mechanic to replace the tires or accomplish a balancing.

The loud noise comes from the engine of my Lexus ES
In case you have discovered loud noise as coming from the engine of your Lexus ES, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected with a compression loss during the engine ramp-up phase, so you should encounter a power loss during your acceleration. If the loud noise on your Lexus ES is related to air intake, the check will be done mainly visually, check all your air intake hoses by a visual control in your engine block to be sure that it is not damaged or disconnected which would cause an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then examine that the engine idle speed is not random. In case you confirm one of these two disorders, take your vehicle to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have perceived comes from the exhaust pipe of your Lexus ES, it is highly plausible that you have rust if your vehicle is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Lexus ES, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To validate this, get help from someone who will stand under the vehicle while you accelerate to find the exact area of origin of this noise. If it is a hole, you can repair it with a putty provided for this purpose, or, if it is a collar, “reattach” it. If it is cut or the hole is too big, it is better to get closer to your mechanic.
