OK, this may seem weird.
I brought a catalic converter from GSF for my Audi 80 2ltr 16v but the olive/silencing ring from my car does not fit the new cat, i cannot find an olive/silencing ring any where that is 6.5 cm across.
The one i have from my car is 6 3/4.
Audi themselves say they would only sell me what i already have.
GSF say go to AUDI.
My mates cant find a thing either from where thay work.
Has anyone else had this problem.
The downpipe is an original Audi part.
So weird. :think:
