The loud noise comes from the wheels of my Nissan NV200
As we have seen earlier in this article, loud noise from the wheels of your Nissan NV200 may be in connection with 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 consider to check 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 change it or them quickly. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Nissan NV200 that is the issue, you will tend to feel a vibration in the direction of the car as you go faster. In both circumstances, you will have to go to your auto mechanic to swap the tires or execute a balancing.

The loud noise comes from the engine of my Nissan NV200
In case you have recognized loud noise as coming from the engine of your Nissan NV200, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be linked to 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 Nissan NV200 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 generate an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then check that the engine idle speed is not random. In case you confirm one of these two trouble, take your car to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have discovered comes from the exhaust pipe of your Nissan NV200, it is highly possible that you have rust if your car is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Nissan NV200, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To verify this, get help from someone who will stand under the car while you accelerate to find the exact area of source 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.
