This is probably the closest thing I have on video to compare the power levels before/after my recent power upgrade. Video on the left is stock motor + 3 inch catback exhaust, essentially a stock motor with more noise. Video on the right is all the goodies: 08 STI TMIC, 08 STI VF48 turbo, Cobb DP, Protune + the 3 inch catback.

I synched both videos as close as possible, you can see by 2nd gear the upgraded version is starting to pull ahead shifting earlier, by the 4th gear change on the modded XT its pulling a whole gear ahead and 5th just kills it.

Its easily a night and day difference.
