The EGR pipe on my '97 has broken again. It was modified to accommodate twin blow-off valves, but they are no longer available (especially the modified ones). I fixed it once before but the pipe is so thin-walled that it is hard to work with. Does anyone know a replacement for these? Even one that has the correct flanges on it that can be modified to work. I currently have it blocked at both ends, but this will more than likely cause a fail during inspection. If the car ever ended up in California it would be an absolute fail I'm guessing so I would like to fix it if possible.
