    • Fabspeed BMW F90 M5 product suite (huge torque gains) - Valvetronic exhaust, muffler, downpipes, secondary cat bypass pipes, and ecu tune

      Fabspeed is rolling out quality products as usual and they have a very nice offering of parts for the beast that is the BMW F90 M5. Not only are they providing a performance boost but wow do they make the M5 sound aggressive to compliment its big power.


      Let's start by going over the pats Fabspeed offers.


      While Fabspeed does offer a tune they did not post any dyno results for the tune. What they did include were dyno results for the secondary cat bypass pipes and their downpipes.

      Look at these results just from changing to the Fabspeed pieces:


      Picking up 60 horsepower at all four wheels is no joke. That is incredible.

      They included a second graph just to highlight how much torque is gained down low. They are picking up nearly 130 lb-ft at the wheels at 2500 rpm showing what a restriction the factory exhaust is.

      Just a major increase in torque down low and response:


      Awesome numbers, right? Now listen below as to how the exhaust sounds. Great stuff from Fabspeed.

        Interesting they used high capacity catalytic converter down pipes. I have wondered why others have not done this and assumed it was due to space limitations.
