I just replaced the muffler on my 1998 Blazer and upon replacing it, I noticed that the exhaust where the cat bolts up to the muffler had a SHITTY weld job and it came loose.... I had enough pipe to put a pipe clamp on it (temporary) and when doing the test drive the Check engine light come on.

 

I scanned it and it came up with P0446.

 

would this be because exhaust is now "bypassing" part of the muffler? (the clamp has already wiggled loose)

 

if not, what in the world is causing this?

 

Thanks!
