What is the significance of removing my intake silencer from my WRX? I got some instrustions to taking it out and putting PVC piping in it. What will this do for me?

Thanx

you can buy aftermarket elbow joint for it that deletes it, removing the silencer is really quite easy to remove.http://www.scoobymods.com/forums/showthread.php?s=&threadid=113

But what is the point of doing it?

Makes the intake louder and imroves airflow.
