Not without mofidying the flange at the cat.
Hangers and positon are ok, but IIRC you need to slice off about 4 inches and reposition your flange.
Huh?

I have fitted a Genie catback to both 1.6 and 1.8 NA's with no modification.

This always assumes that your cat is in the original place, but from the standard position catback there is no difference.

While working to develop the Town and Country catback we have tried this again wth the same results(many times)

An NB 1.8 header finishes well short of an NA and would require some mods(if it were to fit at all)
