welding to the turbo downpipe

[Timmmy]

Hey Eric,

I took a look at youre website (great work by the way) and you have done
pretty much what I want to do, apart from I am being lazy for now (its
snowing outside and I dont want to drive my miata much longer) and am not
going all the way up to the turbo.

I found a place that has the flanges I need (I need 3 of them) and have
just ordered them, although I am sure I could get them cheaper, but I am
out of time.

http://www.stainlessworks.net/

seems like a good place for stainless exhaust needs.

I have the 308L wire and have ordered the parts so I will be posting an
update on my gallery after this weekend.

Thanks again

Timmy
