Hey just asking a question about my Ford xr6 2010 other day I was driving and I went down a curve a little quick and heard a massive thud now when I turn the car on there's a little noise coming from under neath like the exhaust or something, but also there has been a loss of power since the thud as well does anybody know whats up and how I can fix it if so cheers

It MAYBE the catalytic converter is damaged? Might be worth getting to an exhaust place and let them look. If it is a plain 6cyl, you could be looking at approximately $350.00 after market.
