Dear All, Having just purchased a VR6, I am keen to put a new exhaust on it. By that, I mean the bit people see. As far as I am aware the exhaust system(?!) is working, but the 'bit that sticks out the back' is rusty. Can I just buy the bit at the back? If so, what is it called and are there any particular makes that go well with VR6's? How much would it cost to fit it? Thank you so much for putting up with me... Al.
