Re: Ported Manifold for a 98 Grand Prix SE?
sounds good, headers/ported manifolds would give you a kick, but the exhaust/ CAI, and mabe a chip would probly give more cost effective power gains. good luck
you might consider a FWI, make it your self, its relatively easy, and cheap, you cn search old threads for instructions, and i would suggest a straight pipe run from the factory cat to the factory y split, (would take out the u-bend and the resonator) and then just get aftermarket mufflers, both will give you aftermarket performance and the FWI will only cost you 60-65 bucks, the exhaust work less than 250, and the chip 100-200 bucks, ~500 including instalation is not bad at all for the whole setup
