my 04 sti on a mustang dyno made 215 stock to 263 on just a catless downpipe :)

that is a turbo engine no? either way, i'd probably have a hard time believing you got 50hp to the wheels just from downpipes on a 2.5 liter ^.^ specially without a tune or increasing the PSI... But hey, if you show me the graph ill certainly believe it!

I never got a before graph, but everyone said gst motorsports dyno reads around 215 stock. Stock psi was around 14-15, but mine was at 22 after the protune. My stock injectors were nearly maxed out, and 22psi was pushing it for my wastegate. Still lasted 175k miles till i sold it.

increased PSI + tune etc... Touche! that's where the extra power is coming from mostly ^.^ On the previous post you just said you did some exhaust changes.

There's just nothing sexy about it except the car underneath. That tail is atrocious, nothing sleek about its lines, that front has been mistaken for a big 370z by numerous people. The performance sports cars it competes against are all much prettier. I've driven a GTR before, I can absolutely admire the car itself, and I hate Nissans/Infiniti's, but it's butt fucking ugly. GTR is priced like the R8, i8, SL, and 911, and those most would say are easily better looking cars.
