acceleration

That intake is fine for a generic under hood intake, but I'd go with a cold air intake (sucks air from bumper) if I were you.

To answer your questions, I think you lose somewhere between 10-15% power through the drivetrain, leaving you with approx. 125 to the wheels.

You absolutely will not see 10 hp per mod. I think I am very close with the 10-15 hp for all three of those things. Just so you know, when people go get their cars dynoed to see how much hp they are pushing, the number is always to the wheels. So in general, people are talking about hp to the wheels.

You will notice a little difference, and your car will sound very nice, but that's about it. I'd still do it if you don't have plans to ever swap though.

Also, you'd be doing well to see a 5 hp increase after swapping your header, so go with the I/E first and see how you like them.
