this link is to a remus pipe that is a direct replacement for your middle section. I own a 1.8 2001 astra coupe. Will this be a direct placement.. people are mentioning flange fitments? how do i tell if my car has flange fitment..
as if it has if i wanted to get another backbox, can i just go for one that has a flange fitment and is for an astra 1.8 coupe?
