Serious street racing?
If so put the 2500 dollars towards tasers and shock yourself with them. The road is for transportation not kids who think they can drive and end up killing innocent bystanders.

And if you're going to be a serious street racer (what an oxymoron, all street racers are 16 year old and overconfident) then at least research the different aspect of the car before you mod it. Throwing 2500 at a car's performance while still being new to it is going to be a hassle later on because you're reliability will go down as you mod the car and the higher your numbers get.

Most important would be putting at least a few hundred to drivers school/training. Becoming a better driver > having a fast car and not knowing how to drive it.

Everything said above, the 2500 should go to springs/coilovers, sway bars, drivers training, tires, intake, headers, Hondata. If you are goingturbo however you can use the last 3 mods.
And I don't recommend an exhaust unless you're getting it solely for looks and sound becuase there is no noticeable gain to be found, a few hp at most.
