Appreciate any suggestion

Planning on getting exhaust.
I wish to have some noticeable sound different, power gain is not necessary, but no power loss.

I've read some messages before saying low rev/high rev.
Kindly please explain a bit more for me, thanks.

Is BMW Performance exhaust $8K something?

BTW, I love how it sounds! ARQRAY from Japan:

Newbie Q:
After upgrading the exhaust (muffler), the low torque will be affected (slow on pick up)?

I got a ARQRAY for my E87 130i, but I didn't feel any low torque loss.

Eisenmann should be a catback, so it might provide a tiny bit of gains.

Also if i've done my research(lurking) properly. If you have a naturally aspirated engine, by relieving the back pressure you might lose low end torque because the "scavenging" effect. Therefore larger pipes or bigger exhaust, may provide a tiny bit of a power increase up top but in return for loss of low end torque. Hope that helps.

So for a slow driver like myself should not modify the exhaust?

All I want is to sound a cooler on the street.

What to do what to do

Muffler's, would seem like your best bet.
