You have a '98 SE. But is that with a 2.5L V6? Or the 2.0L inline 4? What transmission? Did you want cosmetic mods? Handling? Braking? And while everyone wants more power, that gets expensive quickly. IF you have a V6 and are on a budget, maybe upgrade your tires, swap in svt front brakes, upgrade your rear swaybar, and look into a two inlet main cat fed by two nice pipes from the exhaust manifolds. That mimics the former SHO Shop and BAT y-pipe replacements, as the stock y pipe, even when "optimized," chokes a bunch of power at higher rpm. I found that set up about as helpful by itself as swapping in headers.
