I have a 2001 coupe turbo, and have the Milket cat back section on it. I want to get the pre cat replacement, but on the earlier coupes the cat and the pre-cat is one long section. So i plan to chop it and weld on a plate on the cat to bolt the pre cat replacement to.
So to my question:
The plate that i need to weld on.....
is it the same as on any astra, i.e. if i find a cat section from any astra and cut the plate off will it then bolt to the pre-cat replacement i will get?
Hope that made sense
