I have the exact same set up you are thinking about getting with the 3in cutout and all. I drive with the cutout open all the time! The only time I really cap it is when I'm going on a long freeway trip and have to have the windows up. With the cutout caped I swear this thing is like dead silent! It is just barely louder than stock. I'm buying a Hooker catback tomorrow tho. Only reason I'm switching is for the quality of the sound(cutout is loud and all but it doesn't really sound great and can get annoying) and the tips. But I will keep the cutout and add an electric plate to it.
