I think the power gains will be minimal. 5hp max.

^^ agreed. Switched from something pretty close to the GT4 to the evo and it's pretty marginal difference in gains.

Is it worth changing from a evolution to a gt4 for gains and the note.
Someone on the forum said that with gt4 he felt big gains?

If you already have the Evo, then I would say no unless you just want the car louder.

Man, you have some balls! I've just intalled my Akra Evo and don't see myself doing that anytime soon. Glad you liked it, though.

BTW, I went with the CF tips after seeing your car. CF tips compliment well the SG color. Looks awesome!!!
