Can anybody confirm that 409 399 [left] and 409 400 [right] are the same size?
etka does not state the sizes.

The right side is twice the price, usually a indicator it's larger, more robust.

This is the notorious seal by the down pipe that likes to cook and weep.

It was replaced 4 years ago and it's leaking again, paperwork shows the dealer installed 399 on the right side.

I think they screwed up and if so I have reason to bring it up for replacement.
