Hi all. I have a 2009 WRX (sedan) and I am looking to make some improvements.

I have been reading on lot on these forums and others but there is a lot of info out there and its hard to work out the good from the bad. My car is a daily driver and I don't go to track days or anything like that (not that I wouldn't be interested in that).

I am after some advice about the following performance mods (total budget around $4k give or take - will consider what is needed really).

Goals: more power, more noise (but not too loud or drone), reliability. Not looking to do anything radical and just want to keep it simple and reasonably low cost.

1. Recommended turbo back exhaust?

A couple of options I have been looking at include:
- invidia exhausts (Q300 or N1?)
- CES Racing (New Items-Custom Exhaust Specialists-CES)

Which out of these or other is recommended?

2. Recommend tune method and recommended tuners in South East Queensland region (I live in Brisbane)

CES package above also includes ezy-flash tune.
Keen to understand some other options and recommended contacts to get the tune done.

3. Anything else essential or highly worthwhile?

Grimmspeed 3 port solenoid is a goer based on advice below.

Comments/advice appreciated (totally new to this and never modified a car before).
