Question From whiskeywarden on Audi Exhaust Fix help

My 1995 A6 Quattro wagon the part of the flange that is part of the pipe has rotted so it can not be reused. Instead of replacing the pipe ($$) I thought I would cut the flange off as well as the lip on the other pipe and replace it with an exhaust clamp or sleeve with c-clamps.

Any pros or con thoughts on this?

Response From Tom Greenleaf

The old soup can repair. Wont last but could (maybe) could be fixed by an exhaust specialty shop and put the new right parts welded on. At best it's still a patch job but would/should cost less than the whole parts it should get but don't expect even that to last too long either.

Just my 2 cents and probably others,

Response From Discretesignals

Which flange do you mean? The one between the muffler and resonator or one of the flanges after the catalytic converters?

If the pipe isn't all rotted out, a muffler shop should be able to fix that for you.

Response From whiskeywarden

It is the one right after the cats. Plus there is a cap that has blown apart on the cat that I have to replace.

Response From Discretesignals Top Rated Answer

I'm looking at the diagram of the stock exhaust. I don't know which cat has the broken flange, but as you stated there is a pipe with two clamps where the resonator pipe and pipe after the converter go together.

If the pipe broke off right at the converter can, your going to have to replace the cat and pipe. You should still swing into a muffler shop and have them evaluate what could be done safely and cost effectively to resolve your problem.

Here are the attached pictures of my issue

The part needing to be replaced is over $300. In newer models the connections are connected with the exhaust clamps. They are a sleeve with 2 screw downs on the top. (hard to explain) It just seems easy to cut the flange right out and cover the connection with a sleeve.

Response From Discretesignals

Are those pictures of the flange before one of the converters? The pictures are very small and don't render too much detail, but it looks like the studs are broken. You can torch those out and use bolts and nuts to hold the flange together.

Response From whiskeywarden

The replacement part is $345 (it's an Audi). I saw that other model Audi's have these exhaust clamps that slide over the two pipes and just clamps down over it with 2 screws. That part is about $4.00.

I know it is just a patch but the car has 180k and was given to me free.
