Then you will want Borla or TRD exhaust. But look into that quick at toyota dealers, because they have been discontinued.

Yeah 900 is pricey, and if you do get one pick up a used one. it will be cheaper. And its more for a turbo/supercharger setup kind of tool. Friend hooked it up to his GT like you wanted, it ran alot nicer, but it didnt pass emissions.
