People who have had a collapsed downpipe/xover
Anyone here experienced this phenomenon? Please detail the symptoms for me. Pics are always nice too.

I had a bad downpipe. There was nothing to see. I could not get boost to go over 7LBS even with the wastegate line disconected. I thought it might be the cat so I removed the core. I could look in both ends of down pipe and it looked fine. Tried the golf ball trick and it would not go thru the pipe. I finally cut the down pipe in the center and could see that the inner pipe had collapsed. Replaced with bypass and every thng worked as expected.

I posted a picture awhile back of a downpipe that was starting to collapse on a parts car. If you do a search for posts started by me, you should find it easily.

xover problem
ive had nothing but problems with my crossover pipe on the particular 951 i own right now. i don't know what you mean about collapsing, but mine definitely do a lot of cracking. im on the second pipe and fourth removal, and the short pipe keeps breaking too. i don't know why it keeps happening, my car doesn't run hot or lean; the motor and trans mounts are new...
