    • Stock E92 M3 vs. E90 M3 with full Active Autowerke exhaust race video

      This video shows the difference between a bone stock E92 DCT M3 and an E90 M3 with the full Active Autowerke exhaust including sport cats. So, the E90 is not catless, and the exhaust is stated as its only mod, yet it puts buslengths on the E92. Color us skeptical as the difference is so large. It could be the exhaust is the only difference but the E90 pulls like a car with an exhaust and tune would, likely running higher octane fuel. The video description states speeds above the limiter were hit leading us to believe a tune is on the car and this was left out to exaggerate the difference. Either way, enjoy the video.

        Not really

        filter / scoops $150
        pulley 350
        rear exhaust (any can from 500-7,500)
        turner test pipes or make your own (100-400)
        custom tune $1000

        = 408whp for me. I did it under $2500. Couple used parts and dyno access helps Click here to enlarge

        or you could be an idiot and buy a $3500 akra rear section and gain 3whp........
