?Branches + Freeflow?

Hi All

As you can see, I have a 1998 Honda Civic 150i. I already did the air intake and now I want to get branches + freeflow... there is just some stuff still bothering me.

Now we all know that Honda's doesn't really have the most back pressure of all cars, now the thing is, when you put a branche + freeflow on, you are probably gonna lose even more back pressure, so is this a wise choice?

I basically want you guys advice on this: Is the branche + freeflow worth the money? What are the side effects? My topend will probably be better, but what about quarter mile? Will I feel the performance increase?

Just take note that I am not close the coast, and here in SA, we use 93 octane petrol...
