Hi very good forum !!! Maybe this has been asked many times , but i need to know about my exhaust system on my bimmer. What happens to the performance if i take out the middle can and put pipes there instead ?? Will i lose or gain or non of the above? Please i only want people who know for shure to answer. i know that for many motors you gain when doing this ,, but for newer cars this doesnt have to be true. So only if you know for shure about THIS car 530i Touring 1995.
