Ten-years ago, I installed the Dinan 4.10 in my E-92. It's wonderful through the gears, not making 1st too short, but adding oomph, particularly in 2d and 3d. I used to autocross a lot and it's the perfect setup for that. There is noticeable noise on the overrun, but not too much for most. My wife never complained about it, so it passed one critical test in that regard. It's still going strong, ten-years and 85,000-miles later.
