Hi all:

My main (rear) catalytic converter is leaking at the "seams", which caused me to fail inspection (in mass). What I mean by "seams" is the thin part that separates top from bottom has kinda split near the front flange on both sides. Other than that, it is in pretty good shape and looks pretty solid.

Can those narrow gaps be welded shut. I don't know if the repair would last though. Any experience on that ?

In case I need a new one, I have found 2 cheapo possible direct-fit replacement:

1) CATCO rear converter from www.discountconverter.com

2) WALKER rear converter

Both sell for $99. Any advice/experience on which to get ?

BTW, I have s4 n/a std.

thanks,

They will last for a while. Welding the seams is a temp repair at best

 

I dont know about welding, if i were you i would buy direct replacement exhaust, i just HAPPEN to have stock s4 exhaust that has a new 2nd pre-cat and new maincat that is for sale...

 

thanks for answers so far.

Mel:

If you want to part out your exhaust, I am interested.
I did pm you.

The cats you mention won't last more than a few weeks. Get one from Random or rx-7.com .
