As far as Intake goes tdcracing has a fender well intake thats pretty close to the best your ganna get for the money...

As far as mods got though this will probably lead you in the right direction..

^^ YUP! Don't think you can drop pulley sizes with a cat back either because it does nothing for you.

at least thats how i would go haha. best of luck! happy modding!
I agree on the U-Bend, but not so much on the open cone...you need colder air the less modded your car is. Having a '03 too...they are a b*tch and a half to tune also...thanks to the '04 Transmission and psycho messed up valve body in the tranny...meaning you can't buy a '98-'02 PCM for your car, just '03 specific.

I just sold my DHP Tuned PCM that I bought back in '07 when they were still in business...too bad...but if superv6 ever gets a custom tune for his car, I'm sure he'd let it go to ya

And another thing...READ, READ, READ...that is the best thing to do...especially that thread that I took all that time to write for all you new guys
