Strange Ticking Sound between 1k and 2k RPM

[renaissance]

Mine is 2010.5 E90 M3.

Strange ticking sound can be heard between 1k and 2k rpm only in D or M or R during driving (especially uphill).

I did found a similar thread; however, in my case, no ticking sound in N or P.

Ticking engine sound between 1 and 3K? (remember snowm3)

Quoted from the "m3 weird noises thread"

After engine warmed up sounds like exhaust manifold leak at low rpm, especially with heavier throttle. This is just the way a high revving v8 with awesome factory headers sounds down low. You'll learn to love it after you realize there's nothing wrong with the car.

Third time I've posted this lol. These M engines make a ton of noise, they're derived race engines, it's expected. The e46 ticks and the e92 ticks.

So I can ignore it? Or should it be repaired by change some parts?

BTW, I have Akrapovic Full installed. I noticed leak in the middle before.

Completely normal. I've noticed with a louder exhaust it's harder to hear it
