Like I said to big of piping you loose back pressure and you loose bottom end speed your into street racing but any kind of drag racing acceleration is key. It doesn't matter how fast your car can go if it can't get there in the quarter mile.lol mystery actually the bigger the pipe the ore airflow with adds power and 1-2hp more like 3 but hp is hp we all hustle for that s**t
I've been around a long time n I can tell your just a kid. My civic isn't my first car like it is yours.
