Aside from a tune and test-pipes/x-pipe, there's not much else to get for significant hp gains on these cars, short of a supercharger kit. And dropping 10-11k on a Harrop can be difficult to justify for some. |

I'll give it up since nobody seems to care about potential torque losses, but all the reasons given thus far are just cognitive bias, and don't apply here. Just saying. |

These folks bought a plenum in a group buy to save a few hundred bucks.
It's a bit of a stretch to think they'd be excited about finding a dyno and spending the money they saved on a few runs to get a delta number they couldn't feel in the seat. |

I would have thought an early adopter would have been a big enough gear head to want to see that delta proven. I guess not.

Haimus have had a dyno before and after comparison available since well before the group buy started. They also had a good commentary on how they interpreted it. I read that before I put my money down. My own experience has been in line with that comparison, sure only by feel, not by measurement, but that doesn't make me any less happy with the result. Yes its a lot to spend on changing the sound, but for me the primary attraction of the E9x M3 is the theatre it creates, and the sound it makes is a big part of that. If I wanted a higher hp car, or a sweeter handling car, or a head turner, there are better alternatives. But its hard to beat this car for theatre, and the Haimus plenum undoubtedly adds to that.

I've gone through two iterations of the CarboProject Plenum, which utilizes the bottom factory plenum and a carbon lid on the top half - I found their "Export" version had a higher pitch sound vs Haimus' that has a deep/bass sound to it. Now, that can easily be translated to "louder" but I prefer the more booming sound of the Haimus; it gives it an angry growl.

Came back in town from a long international trip and had a chance to open the package. The quality seems superb with no blemish I can find. And, what makes it very special for me is that my plenum is #100 produced! Install will likely happen next weekend.
