ER intercooler works well for me and is stealth like you said.
In regards to exhaust I would do just the downpipes first and see how you like it.
I've gone through three different exhaust revisions and I am still not 100% happy.

Also you can get a custom tune done remotely by someone like Pro tuning freaks. I have only heard positive things.
