I know it well

There are 4 plastic rivets (2 each side) which are a single use only. Just drill out the centre if each, then the OE diffuser can be pulled out starting one side to the other. The clips/tabs are quite secure though and it is a hard pop in/out.

Which one did you buy?
BMW 1M VO - Cobb + PTF e-Tune, Akrapovic wireless, MadDad mids, ETS 5" FMIC, ER CP, TurboSmart PB DV's, SSK, CDV, OCC, AWRON Gauge, Hankook RS-3's, Vorshlag Camber plates
