Exhaust splutter at low revs

Hi everybody, i bought my car in october and it already had a stage 2 sports exhaust fitted. I sometimes find that it splutters at low revs just coming off idle, i know that this used to be the case with bikes until you got them re-jetted, but the exige is all new to me. Any ideas anybody.

Is it a N/A Exige or supercharged ā€˜Sā€™?

Its n/a exige

Mine is standard exhaust NA, and at low revs pulling away from a junction or such like, the exhaust sort of makes a spluttering/farting sound.
Is that what you mean ?

Yeh, i just didn,t know if it was the sport exhaust that was causing this.
