Okay here's the problem Im having I have a 98 LS 4dr + it's Automatic
Anyways Im trying to make it faster but do to it being a sedan and automatic its harder finding parts. Im not on a buget, I just wanna know what I can do to fix it up..

So far Im already have
~AEM Intake

Im looking into getting
~Greddy 4-2-1 Headers
~Greddy SP2 Exhaust
~Tein Flex Coilovers or is there something better???

Now what else can I get?

My purpose is having it for daily driving & to racing it here and there..
