Hi.
The intake brand is GruppeM. Made to order, waited 1 month for mine. Cost me around $1,000 AUD, landed. Makes a slightly deeper throatier noise. Found it sounding drummy and irritating at first, but then the sound mellowed out like ageing wine, settling down to a nice noise. No power increase by itself, though. Good luck. H
