Default Impreza sport - loud knocking

Hi all, new to this forum and far from a mechanic so apologies if this is in the wrong area!

So basically I have a 1996 impreza wagon sport non turbo. It currently has a horrible knocking noise coming from what I can only describe as below the gear stick area, maybe further up im not sure. It makes the noise when starting, when pulling off up to around 15-20mph, and then 15-20mph back down to 0mph. Not sure if this is a common problem or maybe something silly but any info would be much appreciated! I have uploaded a video to youtube with the link below so the noise can be heard by yourself, if you would like to help!


Thanks in advance, Joe

I think one bushing broke, and you are at low speed/rev... the low frequency vibrations have quite a lot of amplitude and the pipe is banging the car.

Already had this on one car.

Have a look underneath, try to push/pull on exhaust in all directions
