gor the exhaucst i would go custom from meineke (sp?) around 250-300. So far the best CAI is AEM which will offer you high ennd gains, but will leave the torque about the same. you could go with a short ram wich will offer you more low end torque but on hot summer days you can be stripped for some ponnies under the hood. Also for about $60 you can make your own AEM cai with the same gains.
peace.
