What parts are you guys talking about here? Just take car to proper exhaust shop, get them to fix. end of story?
Mine was all rusty, they cut it back to where it wasn't rusty and just made new bits and put it all back together.

Don't rule out the possibility that being in MI the pipe could be corroded to the point of being too thin to weld

(Although what that lack of skill may be, I don’t know. Novice welder me could do it, and an M20 midpipe was one of the first things I ever welded.)

Just get a new flex joint and have it welded to the pipe.

M20 Downpipe Flex Joint Repair?
I have a 1990 325ix that has developed a leak at the downpipe flex joint. The leak is actually on the bottom of the flex joint where it welds to the pipe. The cat has been removed from this car by a prior owner.
A mechanic attempted to repair the pipe, but the repair did not last. When I took it back to him to look at, he stated the pipe (not the flex joint) was too thin to weld and that I would just have to get new downpipes.
Sooooo..... is he right? Or, is there some sort of repair I can do to replace the flex joint that will actually weld to the pipe? I'm open to suggestions!Tags: None
