Extremely Loud & Relatively Short

Extremely Loud & Relatively Short

We’ve got two short videos for you today, but their lack of elapsed time is more than made up for in sound.

First up, we know you’ve been looking forward to more BMW S85 V10 velocity stack action since we posted up a teaser at the end of 2012. Well, during our R&D sessions with Ken’s E60 M5, we were able to whip out the video camera and film a little of the aural action for you. The kit isn’t fully installed during these runs, as we were swapping parts on and off in relatively quick succession at that point in time, so we’ve got three pictures below for you of the full FMU velocity stack treatment, fully assembled.


With the pictures out of the way, let’s move from the eyes to the ears:

We’ve also got one extra video for you. YouTube recently changed the way that their channels operate, and now we can include a minute-long trailer on our channel’s front page that gives unsubscribed viewers an idea of what to expect on our channel. Since we liked the way it turned out, we figured we’d include a second video for you to check out today, as well. Enjoy!

And that does it for Wednesday’s FMU blog post! Check back with us tomorrow for even more original content! Have a great day!

    Sounds nuts!

    What header/exhaust setup does the E60 M5?
    Who did the tuning for the stacks?

    Thanks, Alex!

    The headers are Evolve.

    The custom alpha-n tuning for the stacks is developed in-house, right here on our Dyno Dynamics dynamometer.
