    Just curious if anyone else has experienced a change in the engine sound once you hit 4k rpm at full throttle?? Ive looked everywhere for this and never seemed to find an answer and thought id just ask. It sounds like "vvti" but thats not something the 2rz has. Anyone know what it is?

    Is the intake stock or do you have a cold air intake?
