Hey guys, well I recently traded my 08 WRX back to the dealership and bought a 07 STI...night and day is all I can say. Well its been about almost 2 months and Im ready for some more power. What would you guys recommend as far as first upgrades and taking into account the most bang for your buck. I was thinking about doing a intake, exhuast, and EM with a Cobb AP. The car is bone stock and has about 18K miles on it. Also has anyone seen the Turbo back exhuast for sale on Ebay...they range from about 180-200 bucks. Are these good or should I not even waste my time and get a HKS or something. Also I need you guys opinion as far as good brands to get parts from.
Get the COBB AP first.
The stock airbox is not a hinderence for performance yet. It is also safer to keep it stock for now.The HKS downpipe uses a flat flange at the turbo. This is not good. Look for a bellmouth or divorced wastegate DP. Add a CBE of your choice and you're set. Get quality parts for that Bad A$$ Car.
