N55 BMS Downpipe is installed, along with the Performance Friction PF08 track brake pads.
Install on the downpipes is identical to that of the 335 xdrive - loosen the subframe and they go right in and fit perfectly. For those interested, the brake pad shape is identical to the 335i - any brake pad designed for the 335i will work.
Heading down to the drag strip in about an hour.
