7A 20V downpipe to match Bag-o-Snakes header

[RS2]

I'm on with yet another project and need the upper section of a standard downpipe from an Audi Coupe 20V or Audi 90 20V 7A.

I have the Bag-O-Snakes manifold which collects to a single flange. I really only need this flange with section of pipe so that I can build a new exhaust system.

Does anyone have an old down-pipe kicking around?

Thanks

These are pretty hard to get hold of, I tried and failed a few years ago.
Normally the flange is completely shot. If I was you I'd get one made
Good luck with your search

The flange is just a simple 3 bolt affair if I remember. Would be easier to find on the correct diameter and pcd off the shelf, or have one cut. Saves chopping up a usable downpipe if that's all you need.

Its the 4-bolt flange where it mates to the centre section that normally is in **** state IME.

I found a pattern one once might have been on ebay worth looking.

Hmmm,

Fair point.

Is a 3 inch exhaust too big for a 2.3 20V 7A?

Yeah mine was a bit grotty but still usable with some washers.

He's only after the upper bit to mate to the headers which is why I suggested the 3 bolt flange.

What size is the oem exhaust?

OEM is 2.5" IIRC, 3" is too big really.

That's a shame. I have a 3 inch proper chambered silencer I was going to use on it along with a straight through to keep the noise down but high-flow.

Maybe not enough back pressure for scavenging?

Hmm, it doesn't seem the right shape to me, looks too long / tall, could be wrong though

[Kieron20V]

I don't remember mine having that bend halfway through it.

If it's 2.5" is say buy a 2.5" 3 bolt flange and if the holes don't line up, just elongate the holes slightly, shouldn't be ways out.

You can see my original one in this pic of my old 7A:

Yeah, the ebay one has a weird kink in it though.

As i said, id get a flange like this and make it fit.

I've had a look at the part I posted above...the reference number is 70311....it fitted mine spot on ( although I de-catted it and linked it to a double skinned stainless flexi joint before the rest of the exhaust to reduce the usual cracking risk at that section )
