Other than a Silicone Y Pipe, I never did any power mods. That's not to say that power mods aren't fun and rewarding, but just not something I had a chance to do.
If "Lbleiweiss" was rolling in a 02-05 WRX I would have told him to get an uppipe first, to get rid of the cat there, and I would suggest that to any 02-05 WRX owner. I never had a chance to do that before I sold my car.
The larger sway bar made the car more level going around corners, making it possible to go around them faster, making it more fun
. Like I said in that post, pick up a 22mm adjustable sway bar, and also pick up an ERZ uppipe (if you're rolling a 02-05 WRX). Cheers, Jeremy
