Exhaust rattling can happen due to broken rubber mounts. You can get these checked from any silencer shop. They also keep and fit these mounts.

Rattling sound is when exhaust is touching the body of your vehicle, that is possible if you hit your vehicle on a bump. You mention it is at idle I think that is more likely the case, if not then it seems unlikely that the rubber mount has broken since in that case you would hear vibration throughout the drive and not only idle.

Would suggest visiting Jail road side right next to the bridge is an exhaust repair person, if you reside in Karachi it can be fixed today.

If it has catconv then probably its broken.

Yes for sure It has a cat converter

But bro today engine starts misfiring at first then after sometime the exhaust gets louder and now if I am reving it it is perfect but with louder noise

Plz tell me if it is still misfiring or not

After listening to this I agree with the member above that it seems like a broken cat converter. It isn't simple rattling of exhaust due to broken mounts.

Does my car sound fine

[UAHMAD]

No. You didn't consider it normal yourself. That's why you posted your question here.

Please get it checked from a reputable workshop ASAP.

You're exhaust muffler might have rusted and broken from inside. It happens
