I want the Greddy EVO cat-back exhaust, but mainly just for the sound, and the HP, but I was wondering how much can I expect to get out of it. My car is all stock with 140HP = ( Will I break 160HP? And if I add Cold Air Intake and Underdrive pully kit, how much am I lookin at total (HP)

most exhaust modifications give you 2-4 HP max increase, and you lose a little low-end torque (launch). BUT your top end on your gears will be a little stronger.

id really doubt you will even see 160at the crank

let alone at thewheels is no where near 140..

not a huge gain plus
a cat back on ourcars really isnt needed
the stock piping is good.. just add a muffler

Muffler 4 hp, intake 5 hp, pulley 10 hp.........

All together I would guess 15 hp increase.

The age old question.... No, you will not come even close to 160 hp. The CAI will yield you 4 hp max. The exhuast will yield maybe 6 ponies max. You're looking at ten ponies for $600.00. You can also see this in this months issue of Import Tuner. My suggestion is for you to (a)get NOS, (b) save for turbo, (c) sell your car and save up for the GS-T.

put some stickers on ur car, gain 20hp haf
