Recommended First Mods to new WRX
I have an 03 WRX sedan and want it to be faster. What are the best mods for under $1000. I have been lurking around the forums for about 2 hours and i have taken away that exhaust mods are the way to go for initial stuff. Up pipe and down pipe is what i am thinking, or possibly exhaust system. What do YOU think. All opinions are greatly welcome. Plus, i was thinking of a blow off valve for the sick sound.
P.S. I sould probably note that my car has just over 10,000 miles on it and i drive on average 100 miles per day at 75-85 mph (3000-3500rpm). I dont want any mods that will shorten the life of my car considering that before the year is up i will put on another 15,000 to 20,000 miles on it.

this is what i have done so far to my MY02 silver rex. I have done a modified version of the silencer mod. Instead of removing the silencer i took a hack saw to it. I still retain the stock ram air piece under the hood and the large baffle on the silencer is removed so i take in air from grill and fender wall. I havent heard what it sounds like removed but i like the rush sound of the air now. I also added a drop in k&n air filter. Just bought a turbo xs axle back will be installing this weekend and painted my calipers blue with G2 brushable caliper paint. I plan on also doing up pipe and downpipe along with some other handling mods and brakes. I hope this helps a little

depends what you're interested in most...power or handling.
i would suggest working on airflow first; uppipe!!! when you get rid of that preturbo cat, your turbo will wake right up, boost will come on earlier, and will have a better overall flow. a good mechanic or someone that's familiar with doing uppipes can have it done in < 3 hours.

So I have a silver 03 WRX with ~1800 miles am in the same boat... You say you want it to be faster... do you mean top speed, quickness, or more torque? Is your $$$ just for the engine? Do you see yourself bugeting any $$$ for handling?
You might want get a ECU reflash (i.e. Vishnu Stage Sub-Zero) it 3+ times the cost of an uppipe but you get 3+ more HP as well. Your chances of voiding any warramty are minimal and I hear it is way faster and alot smoother as well...

Thanks for the info guys. I am really interested in second and third gear acceleration. More torque i guess.
if you read this section of the forum, I pretty much get the idea that cold air intakes are detrimental to the life of your engine without proper tuning. CIA's can lean out the mixture and f-up ur engine in the long run. Will an Uppipe do the same?

all the exhaust mods are after your a/f mix, so you can't really lean it out, so they should all be relatively safe.
I only have about 450 miles so far on my car (in 3 days, and i already moved someone to a new place :-P) but my first mods will be along the lines of this:
uppipe and downpipe
rear sway bar (probably 20mm or 22mm)
then i'll probably start looking into ecu reflashes and a "quiet" aftermarket exhaust and suspension/wheels/tires.
