Letting off clutch in 2ND Gear?

[Chris87]

bit of a weird problem i have a clio 182 and when i put it into 2nd gear and let off the clutch there seems to be a boom noise coming from the back end and i only have the standard exhaust on does anyone know what this is?
cheers

sorry its when i let off the accelerator

exhaust mount might be gone allowing excessive movement of the exhaust pipe??
or an engine mount, once again allowing too much movement causing the exhaust to hit on something?

Yeah that does make sence only happens in 2nd gear and it's fine once car has warmed up might just get a janspeed exhaust this is the 2nd time I've had problems with the exhaust thanks for help mate
