My 1.4 GTC is  getting near ready for the exhaust to be replaced. ringing around. it seems that everyone is telling me that its hard to obtain and that Vauxhall dealers are the ones i should try. So, i rang the local dealers and even on my trade club account, it is £498 for a secondary cat back system.

Hoping someone can shed some light on this. I have seen a cat back exhaust system for a gtc 1.6 turbo. Now my car is a 5 door 1.6 turbo so would it fit on my car as I cant find a system for it. Looks the same in the pictures but not sure. Maybe someone knows if the standard exhaust systems are the same part number?
