I have a 1985 528i e28
the system i have running on car is twin from manifold into first muffler( stainless steel) then single 50MM steel to rear muffler (stainless steel) then out past the bumper in stainless.
I was thinking of twin pipes and twin mufflers from the manifold through out the system ..
i am sure the M535 came standard with dual or twin muffler systems ..
Anyone had much to do with 2.8 and the perfect sports/style exhausts i am seeking advice on which way to go ........... I like the twin through out in all stainless 2&1/4 inch bit big for the little engine???? whats the go any ideas?
here are some pics i have found on the subject .. thats not my car...
