Random technology offers a "high flow" Y-pipe. Slightly larger pipes and two high flow cats for about $550 that is a direct blot in and should yeild about a 10 HP gain ( not very exciting ).

Shorty header kits are all going to run over $1000 as the come with y-pipe and cats. If you go this route the MAC headers are a good unit for the price. you can expect a 20-30HP gain.

Long tube headers will certainly give you the most HP, 30-40 HP gain, but you may have trouble getting thru inspection and ground clearance can be an issue if the car is lowered.

Just some options to think about.
