people with oem exhaust mod please step in

i have a question...poeple who did the mod did you feel any loss of power? i dont want to do the mod and be unhappy with it if it lost a crap load of tq... any input would be great... i was thinking of just taking off the axle back and getting custom straight pipe axle back instead so if i dont like the sound or need to brig it back to bmw for warrenty stuff i can put the stock back on
