Gen1 Roe Exhaust Question

[Much]

I removed my Roe HF cats a few Years ago when i did my Greg Good Heads and Cam but i cant stand the smell anymore and want to but them back in.
Is there a Flowing direction of the Cats ? I cant find any Information on them , maybe someone has a Picture of the Roeracing 3" Exhaust on a Gen1.
Was the Cat closer to the Muffler or closer to the Headers because the Cat has a longer pipe on one side.

You typically want them very near the primaries. The G1 & 2 cars had them in the front of the sills, just where the turnouts went parallel to the centerline.

Austria and you are not on jail for running catless?

They need to heat up to 600-700C, so as Dean stated, close to primaries.

My Idea was to put them close to the Headers and put a second muffler between the Cat and the big Roe Muffler to get rid of some noise and smell. The Law is getting very difficult over here
The Roe Exhaust was so Common back then but today i cant find even 1 Picture of it on a Gen1 Car .
Is there a Flowing direction ?

Cats are bi-directional. I would recommend Moroso Spiral Flow mufflers. They come in 2.5 and 3.0 inch diameters. Very nice low rumble, not raspy or loud. Do you have side, or rear exhaust?

Hy Dean i have the Spiraflow Mufflers at home but they are to long to put them between the Cats and the Roe Muffler. I have Side Exhaust .
Thanks for the info that the cats are bidirectional that helps a Lot
