where to find turbo header parts

I'm in the process of building a Turbo header for the TOAD and I've been shearching the net looking for 1.5" butt weld elbows 90 and 45 also a 6 to 1 merge I found some on eBay and I'm almost ready to pull the trigger but I was wondering if anybody has found a outlet for header parts I'm looking for stainless but if the price is right I'd even use black pipe
alittle help is always appreciated
