1fz-fe vacuum leak? Or just normal? (1 Viewer)

I have this interesting sound when at highway speeds, it seems to be dependent on throttle. Kinda funny, my motor is NA but sounds otherwise...

Motor has like 15k on it, intake tube new, vacuum lines also replaced (back when the motor was done)

These motors have this sound or should I be looking for something?

That's the exhaust whistle from the weep hole in the bottom of the muffler. Totally normal.

It gives you the feeling of a turbo without the expense or power.

oh wow, thanks! I have a different muffler but im sure theres still a weep hole, maybe thats why I now notice it compared to my old OEM tired exhaust system...
