Strange place for me.

First post for me, this is a weird place for me to be having a full bolt on and tuned Mitsu Evo X . I've learned a lot reading this forum for the last couple of weeks but there are a few questions I couldn't find the answer to.

I'm trying to enhance my fiance's 09 yaris hatchback a/t, I already did a drop in K&N. She was complaining about highway speed handling/cornering so I just purchased springs locally(lucky to know Paul from Dezod personally) and the 19mm ultra rear sway from micro image. I've been reading this site for a while and I've been looking for a back to back dyno sheet comparing the stock exhaust to the TRD or anything similar to see exactly what the gains would be, not so much even the peak numbers but the area gained under the torque curve is my largest interest. I looked around and most times there are multiple mods added at the same time skewing the numbers.
