Clunking sound
When i step on the gas there is a clunking sound coming fron the exhaust system, everything is new execpt for the catlitic converter. It usually only does it when the car is cold. If i excelerate hard and then let of the gas it will clunk 2-3 times.
What could this be??

Thanks a lot

If it's the exhaust system it could be hitting on lots of things, especially if you got oversized pipes. It gets real tight up and over the rear axle especially near the control arms and along side the fuel tank.
Easies way to get it on a lift and start looking
