Stillen has just intorduced their new exaust, and currently have full length headers being tested and will soon be released to the public. My question is what kind of number gains would be expected with say the stillen exaust, full length headers, and the ingen cai all runing together? I know it would be hard to put out an exact number but for those of you that are into the import scene and know something about all this please take a guess. Im new to cars, and looking to make these my 1st mods and am trying to figure out if its worth the price for the gains.

Thanks in advance!!
