Scorpion backbox fitting

[Toby_Unna]

ok another blatant abuse of zone knowlege for my own benefit!

have Scorpion stainless backbox on my 1990 320i

i know nothing about M20 cars! the system had two boxes, and the rear section comprises backbox and separate joining pipes which mate to the other (front) box.

will it fit all 325i and all 320i, or only certain models of each, or only faceleft 320i?

thanks again!

my scorpion system on my 325i consists of rear box + centre section fitted to bmw dowpipes and manifold its twin pipes all the way through
