Eisenmann performance exhaust f90 slower?
Installed the axle back Eisenmann performance exhaust on my car. I also have the m performance "resonator delete" the mid pipe. Anyways, since i have installed the axle back Eisenmann performance exhaust on my car I feel as if the car has become slower 0-60. Was wondering if anybody else has felt this or has a clue. Thank you

http://www.gomog.com/allmorgan/exhaustbackpressure.html 3. How did the myth about back pressure and big pipes come to be? I believe it is/was a misunderstanding of what is going on with the exhaust stream as pipe diameters change. For instance, someone with a Honda Civic decides he's going to upgrade his exhaust with a 3" diameter piping. Once it's installed the owner notices that he seems to have lost a good bit of power throughout the power band. He makes the connections in the following manner: "My wider exhaust eliminated all back pressure but I lost power, therefore the motor must need some back pressure in order to make power." What he did not realize is that he killed off all his flow velocity by using such a ridiculously wide pipe. It would have been possible for him to achieve close to zero back pressure with a much narrower pipe - in that way he would not have lost all his flow velocity. Are the valves functioning correctly?

Unless you have a leak, there should be no change in performance
