before I start asking my question, yes, I am a ricer... guilty as charged... :
Now I got APR Stage 1 tune, PD160, K&N drop-in filter and APR R1 DV, the DV dumping sound is definitely a lot noticeable than stock, but still not as loud as some youtube videos of cars with similar mods... it is still very subtle...
how do I make it louder?? without bypassing N249, is there anything I can do to make it "pssssssssssst" more??? Cheers....
