Nasty Vibration on Clio 197

Hi guys,

Hoping you can help with a little problem which seems to have developed yesterday.

I've noticed when stationary at a junction/traffic lights etc my car has a vibration that you can really feel through the seat, if you touch the pedal lightly to increase the revs the smallest amount the vibration disappears. It's not felt again until going from 60-70 in 6th gear.

I've recently installed coilovers and had to go over an island of a speed bump the other day during I could here something scrape, so now wondering if these two things are connected.

Would appreciate any help.

Ok, will get the exhaust checked. I've noticed this morning that it's only when the engine has fully warmed after 15 minutes or so.
 
I have a similiar vibration which causes the steering wheel to vibrate ever so slightly. Also disappears when I blip the throttle. I know for a fact that my exhaust is out of alignment. So thanks fox will look into this.
