2003 Audi A4 1.8t (B6) Flex pipe size?
 

Alright, so I recently hit a sewer grate and sheared my flex pipe in half just south of the downpipe. A good chunk of it is missing, and I've seen varying information for sizes of the pipe. So...

Does anyone know what the length of the stock flex pipe is my model (2003 A4 1.8T B6)? I've seen anywhere from 4" to 12".
