    Supersprint before and after F30 335 N55 dynographs showing the difference between stock and full exhaust with catted downpipe

    Some useful information here from Supersprint showing stock versus full exhaust only output numbers on an F30 335xi. Supersprint is using MAHA dyno which is a popular dynamometer in Europe. What is important to pay attention to here is the delta between stock and with exhaust. The F30 335 output with the stock exhaust is measured at 307.1 crank horsepower. With the addition of the Supersprint 100 cell catted downpipe, 80mm pipe, and mufflers, output goes to 318.2 horsepower.

    This is a change of roughly 11 horsepower. Not huge but about what one should expect with a catted downpipe and no tune. These numbers would radically change before/after on a tuned car with more exhaust flow but on the stock tune the stock exhaust system does not appear to be a large bottleneck.

    Charts below.

    You are absolutely right. I have little experience with these dynos.

    What I love about the maha dyno is its drivetrain loss calculation. Shows very clearly how drivetrain loss is not a static number but exponential with speed.

    Definitely agree on that.
