I just ran into a guy that made one of these H pipes from scratch....looks
overkill but effective.  He could be coaxed into making more if their is
enough interest.  I don't know what it's made of although it looks metallic.
I have no specifics about this part other than he made it, it apparently
works, and it looks overkill.  I don't have a 1.9 so I wasn't too interested
but I keep reading posts like this so if you have an interest, please shoot
me a p-mail and I'll count them up and see what he would charge to make
more.
