Hi dudes. Got a Saxo VTR in zest yellow. All complete like, nothing hanging off BUT...there is a slight knock from the exhaust now and again. I've checked the connection to the engine, all fine, and the blow from it, all good. I've then checked how secure the exhaust is to the vehicle at the back box. Can't move it much up or down so all good, very secure there. But, only occasionally, when you go around a mini roundabout or something, the exahust seems to shudder and knock against the bottom of the car. It does shudder in the middle when the engine idles but only slightly. When you're driving normally, or even quickly, its fine...don't notice it. But, just occasionally, when you go around a mini roundabout or do a slow speed move, it knocks against the body just for a few seconds then stops ??
Any ideas??

Maybe its a lost bracket in the middle? Or maybe I'm just noticing something that isn't really important?? At first I wondered if the shudder was being caused by the car being at too low revs in higher gears at slow speed (naturally) and therefore the shudder from the engine caused the movement??
I don't know really!
Just wondering in case its something serious, but hopefully not so 
Cheers guys, be safe
