Intake question

TripleBlkZ

Ok let me be honest here, I know nothing about intakes only what I have seen on the forums. I don't think I am brave enough to attempt any work on my Z unless its totally simple.
Currently my 2010 ZR is a cruiser, I will never track it. I just want a small modification that will set me apart from a stock Z.
I am looking at either of the below intakes cost not a huge issue but want to stay reasonable.
-stillen's gen 3 intake or STILLEN Generation 2 Long Tube

Most likely have a shop install either one but need some opinions on the following;

1-between the 2 intakes which if at all of the 2 will have the lowest addition noise? top down is loud enough looking for the lest amount of added noise.

2-easy of install and maintance if needed? if I feel brave enough to attempt.

3-and bang for the buck..have a rough idea of part cost (CND$), no idea of shop cost to install yet.

4-anything else I would need to know that may add additional cost.

Any advise is appreciated....
