Rear diffuser modification

[GlobalPilot777]

Found this on the internet and this CF rear diffuser looks sick to me! I know its a render but the one who came up with this gets kudos! Also love the rear CF slotted engine cover.. defo a big weight safer, and with the roof scoop like a mcl600lt maybe you a better or extra cooling aid. Would defo buy this if I can get it custom made somewhere. If you know companies who can do this let me know

Ps diregard the high wing and wide body.. not my cup of tea
