Hey Did you ever get the fix on the 97? for more power long intake, exhaust headers to flow through cat ( no baffle ) to can type muffler. Crank pully change to aluminum, then turbo if money permits.Exhaust pipe to 2-2 1/2 in dia. is good. if you have a smog ck like ca. does, caution on no baffle cat.
