Hey everyone. Can anyone tell me if you need to put in a programmer on the 750i brutes when you put on a full or slip on exhaust. I hear both that if you dont it runs bad and if you do it will run bad. Alot of people said no tto put one in but i am not sure and if i do which one should i go with. Also which is better the full or slip on and what brand. Thanks
