2002 Legacy GT wagon. about 62000 miles. Stock/OEM Headers.

 

Front left side header pipe cracked in half at the base of the y-pipe...where the two pipes merge. Sounded kinda neat...but to keep the neighbors happy I had a muffler shop cut and weld in a new section of pipe. Anyone else here have this happen to them? Are both right and left sides prone to cracking, or just the left?

 

Thanks!

I don't know how common you problem is....but I would say from an engineering point of view that the point where the pipes come together will have more thermal stresses, and probably over time the weld failed.
