I need a new front end pipe section and it is no longer available from Volvo. Any advice about where to obtain one?
Eurocarparts, or try a local tyre / exhaust fitter.
I have often found that these stainless steel exhaust centres can custom make and fit exhaust parts cheaper that buying and fitting yourself. They should last alot longer too.
Surely most stainless steel systems do not use stainless for the front pipe.
