Hi
As suggested I tried Ebay without success. At the moment this is the only thing I have found:
Universal Megan Racing Flex Pipe - FLEX225 by Megan Racing
and I'm not that convinced about "universal" fitting especially as it does not appear to have any flexibility either on the length or the pipe diameter. DOes anyone have any idea on what diameter and length I need for this 2008 Aveo5 please?

And why is it the only piece of exhaust I don't seem to be able to find anywhere in America??
Frustrating ain't it
