So I’ve seen these people doing the cheap diverter valve mods on n54 to here the “blow off” sound. Is this possible on the n55. I can’t find where to do it or if it’s possible. Thanks
Not possible. Doesn't have an external valve like the N54 does.
I believe, but am not certain, that it is integrated at the inlet of the turbo. I know the 4 cylinder is like that, and I am pretty sure the N55 turbo is the same way.
