K & N short intake...opinions

Shamrock

I bought my car a couple months ago and already have the bug "stronger, faster, louder". Problem is I pretty much haven't filled my pockets up yet after the big purchase. In my country the car costs 80k. I thought about the K&N short intake as seen in the picture. I know there is almost no recognizable hp gain. I am interested in having the engine sound louder; more of a roar. I don't want the longer pipes because I can't pass inspection with any intake kit what so ever and I don't feel like taking off my bumper every time a cop stops me and sends me to inspect my car.
Questions :
1. Does the K & N make the engine considerably louder at wot?
2. Does it in any way cause harm to the engine?
3. Does it mess with the ecu?
4. Would an ecu upgrade from uprev be worth it at this juncture when all i'll have is the intake system.

Thanks
