i have a crack at the Y of the rear exhaust pipe on my 02 rk. ive checked out a few threads on this and havent really seen anyone who sounds like they've welded it. seems like most of the opinions fall in the category of just buy a new one. there have been some comments about metal fatigue and weld failure. i'm lookin for some comments from welders who have worked on exhaust pipe. my thinkin goes along these lines: if u can put a good weld on a relatively soft but thin steel, u should be able to put a good fix on a stress fracture in the exhaust pipe. the steel looks fine. i think i can prep it to take a good weld. i'm thinkin that an oxy/acetylene torch weld with a reasonable filler metal should fix somethin like that crack just fine. i know the devil is always in the details, and the detail here is that the metal is so damn thin. but with the right torch tip, can't this be done with a reasonable result? ok, lets hear from some of u torch poppers and sparkers out there, who have done this stuff. thanks.
