Saleen offers the same warranty with Ford...I went thru that....dont be so sure on the Roush. if it means anything I looked at both very long hard trying to deceid. But the more I read and saw the Saleen was on top

Im very happy with mine and it still not tuned right. just installed it 2 weels ago. all I can say bad is the Saleen tune sux for the auto
tranny cars! other than that is great!! tune soon to be changed....I was worried about my warranty but....thats out the window now....nothins goin to happen anyway
