I got my B5 S4 Chipped and put an intake and stay up with modded STi's... I beat stockSTi's pretty easy...My friend has an STi, Check out the site I have posted below to seeall the parts... It's got LOT'S of ****... And on the freeway, starting at 30 on 2nd gear he pulled a little and also pulled on 3rd... I caught up in 4th and passed him pretty good on 5th... I have a short vid if you would like to see...

I love my S4, I love the reliability, other then sensors going, but so what that is easy, and it looks a hell of a lot better then any jap car. just my opinion though. the S4 is as sporty as I wanna go. thats why I have the A6 for grocery getting
