Why is my Vauxhall Insignia making a loud noise when I accelerate?

I recently noticed that my Vauxhall Insignia is making a loud noise when I accelerate. It seems to be coming from the engine or exhaust. What could be causing this and how can I fix it?

It could be a problem with the exhaust system, such as a leak or a damaged muffler. I recommend taking your car to a mechanic for a full inspection and repair. It's important to address this issue as it can affect your car's performance and emissions.

It's possible that your car's air filter needs to be replaced. A clogged air filter can cause loud noises when accelerating. Check your owner's manual for the recommended replacement schedule and consider doing it yourself or taking it to a mechanic.

Another possibility is an issue with the engine's belts or pulleys. Over time, they can become loose or worn, causing noise when the engine is under strain. I suggest having a mechanic check and replace any damaged belts or pulleys.
