Any intake will allow a small bit more noise.
Is it worth it? Only you can answer that ???.
I personally think it's not worth it and wouldn't change the intake unless you go to a stage requiring the hpfp upgrade or a larger turbo. I ran a performance oem filter replacement in the filter box until I went K04. Also...I have seen results by a Tuner in an article meant to show the HP results after installing both a turbo-back and intake. The baseline average was established...then the Intake was installed and all pulls showed only zero to 4 HP on one pull. Then the Turbo-back was installed and again showed just zero mostly to 4 HP above baseline. This was done before loading a canned tune requiring the intake and at least a DP.
You will lose the engine cover if the RAMAIR is a full intake tube...which isn't completely a bad thing. Often the engine cover/filter box, is partly responsible for why the "fuel pressure regulator-N276" ends up broken on the HPFP. People removing and re-installing them carelessly causes the N276 connector to crack.
I have a few vids of me just driving around which you may want to listen to. I recall it was quieter some 11 years ago. Remember, mine has a K04 so it may produce more sound than an intake on the stock K03 with an intake:
