If you dont want to get headers your best bet would be to get the mufflex stainless steel offroad pipes. They bolt in place of the cats between the exhaust manifolds and ypipe. People sell them used for $100-150. They will give you about 10hp.
Its hard to beat headers. They save 40lbs and add 25rwhp along with increasing gas mileage.





Damn that stock thing is ugly though.
