Hi everyone, one day i was bored so i decided to do the ice box thing for my hatch, it sounded very aggressive without my exhaust, but then after i install my exhaust it was slow, so i decide to put the whole stock intake system back on, and it pulls very hard, very good! But the thing i wanted to know was since the si model came less restricted does the stock intake system have better air flow than after market? i don't know because i do not have one at the time, thanks
