i have same problem in my l99 , i feel the hesitates in the first monthes but i'm didn't take it in seriously because it was happening to me at low speed and i dedn't changed my exhaust that time , but now i change my exhaust system and usually i drive my car in high way and i'm just feeling the hesitates and with the new exhaust it make high noise during driving and i feel that noise aulso when i puting in cruise control at 140km , i thought this noise comes from the exhaust at the beginning ..
the thing which i'm not know why it's happen , during i'm driving in high speed and the cruise control worked in 140km , i try to change the gear shift to manual and the sound is just desappeared !!
so ,, if any one the same problem happened to him and he fix it ,, tell me what u did ...
