What Next? Headers, TC, other ideas?
I have been talking with my shop out here trying to figure out what mod to do next. PPE headers and PI Torque converter (and tranny cooler) are both on my list. They have recommended doing the headers next and then going from there. I am asking the Club for your input. What do you think I should do next? Headers? TC? Valve body upgrade? Other suggestions? I always love hearing what you guys have to say.
Thanks,

The headers are great and I can recommend it to any GS4 owner. Be warned that the install is hard though.
I only rolled with the headers alone for about 1 week before the intake+ecu, and it still made a pretty nice difference, the mid range felt a lot better.
Now with it all combined, past 4.5k it really feels way better, I had just the axleback before and it doesn't even sound like the same car.
It's still very quiet though, if I drive gingerly i bet pedestrians 15 ft away couldn't even pick the car's noise out from traffic at all. I don't think passengers would be annoyed by it. You could just crack your window 1 inch and it would cancel out any drone in city driving.
Overall very happy with the PPE headers, I think you will like it, and it's not loud at all.
Only problem was, the steering shaft kind of rubbed on the driver header but it stopped after a week, and it's been fine ever since I think it ground itself a little clearance

Your car looks great BTW, nice to see the stock chromes in good shape, and the grille looks good too

I want a TC bad but i kind of want a GTE swap..but I'm conflicted right now since my engine+trans still works perfectly. So let us know how those upgrades feel once you do them!
