Day 9; 706KM, springs finally going in Wednesday!
Got a few ideas on the table at the moment.
Firstly is the exhaust, from the factory it's actually quite audible (similar to EVO X noise level) and even getting the backfire on the back-off, but it looks terrible.
So the idea is grab some quality 3.5"-4" tips (similar to the ones pictured) that will fill the bumper cut-out better and also get the resonator cut out of the exhaust also. The resonator delete is popluar with the MPS crowd and gives the car more growl without being overly obnoxious like many cat-backs, and for the $140 I was quoted for the job it isn't to expensive either.
Anther part I am trying to secure is a COBB Accessport. This will allow me to remove the
1st/2nd gear boost limiters and gain approx 10% more peak power and 15-20% more peak torque 
because I don't have enough torque steer. It can also reload the stock (or any other map) in minutes so my dealer won't even know
Plus if I do upgrade turbo/exhaust/intercooler/fuel in the future it can have a custom tune with the AP as well.
