Thanks Larry.

I ended up making my own "Y". I just wasn't sure about the metal type
of the Jetta "Y", thus was unsure my welds would be good.

And as for flanges, I used a local fabricator/welder to weld the pipes
to flange that mounts to exhaust manifold.

I didn't know there was a wire for joining SS an steel. Good to know. Thanks.

Neil.
