I have an extremely lowered car, the exhaust pipe moves, squeaks and clanks at times. The sounds are not so bad on smooth surface roads.
I had been getting a knocking sound from under car and just left of clutch(i'm right hand drive). This knocking sound was very bad earlier but seems to have calmed down but with that calming the exhaust sounds have gotten worse. this makes me think the knocking sound has something to do with the exhaust pipe. I think this sound is more pronounced on non smooth roads.
Besides the fact that you can move the exhaust with your hand and it often scrapes humps, there are no visible problems with it.
If the knocking sound is related to the exhaust pipe, can you think of what may be causing it?
I had the suspension checked and they didnt find anything that maybe causing the knocking sound. The driveshaft maybe causing the sound but for the reasons mentioned I feel it might have something to do with exhaust but not sure what might be wrong with the exhaust pipe such that it would cause a knocking sound.
