Stepping up from a single 450 to this dual setup was night and day. Logs at 30+ psi are flat and clean. The fact that everything fits in the OEM bucket location is a huge plus, and the wiring took maybe an hour following the included diagram.

What people say after the install
A few recent ones from customers who did the install themselves.
Fit my F30 330i without issue. Install was about four hours including dropping the front diff. Sound is noticeably better and the car pulls harder after my JB4 tune. Welds and bends look professional throughout.
Perfect fitment front was easy to install but the rear is a bit more complicated haven't gotten around to do it yet but will. Handles way better on turns happy with the results thanks.
My M240i destroyed the OEM charge pipe every at 22 psi. Installed this and have had zero issues since. Boost holds steady all day, every drive.
Picked this up for my F30 335i build going stage 2+. Install took a couple hours but the directions were clear. Pressure logs are textbook now, and the tuner sent the new map without any issues on the dyno.
G80 sounds incredible with these installed. Took some time on the lift but everything went together without issues. The bracketry lined up perfectly and the welds are clean.
