After few miles of driving, when I shifted on neutral or parking and step on the brake, I hear weird sound from rear driver's side. it sounds like similar to standard exhaust like "dung dung" every 5 seconds. Have you guys ever experienced this? I don't know what the problem is....

 

i experienced this today after drag racing my friend. It was that and burnt clutch, i expected the spell of the clutch not so much this weird sound it stopped after a while do i ignored it.

 

i hope it disappears soon...
