Thats why I say just leave it stock on sec 3. For performance it is still good to go. Spend the money on headers/2 AR 20s/Rogue Sec 2 w/EVC (when you want loud power). You can adjust the valve for between wide open and shut to what you want. I leave mine about a quarter open to get more of the thumpy sound that an STI makes with a little bit of back firing. Wide open, its a monster now. Closed with Eisennman it sounds very close to stock and not worth the money as it does not save a lot of weight either. If I were to change it up I would go with something that weighs less. The rest is just a waste of money. For all the stuff mentioned you are looking at about 1200 if you go JVT headers. My JVTs have been doing extremely well as are many others. This would give you much better power and a controllable sound.
