Default Exhaust Piping Question?

I have a 2000 Acura Integra ls































Question is will a 2.50" pipe diameter exhaust system hurt it or should I do a 2.25" pipe diameter? because I don't want to lose power, I want to gain more power.































Note: I'm also including the header size to, as in if I do a 2.50" system the header collector is going to 2.50"

That's not going to happen. Gain or lose.

Back pressure: The myth and why it's wrong.































One of the most misunderstood concepts in exhaust theory is back pressure. People talk about it with no real understanding of what it is and what it's consequences are. I'm sure many of you have heard or read the phrase "Engines need back pressure" when discussing exhaust upgrades. Sadly, that phrase is completely inaccurate and a wholly misguided notion.

some good reading from Brent































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.
