Where is a good place to buy stainless steel flanges and pipe to build custom manifold.....I have been trying to decide what manifold to buy after having so much trouble with my last one and I came to the conclusion that why not just build my own and see how it works...my plan is to build it out of 316 or 321 80 guage stainless steel...the chances of cracking will be a lot lower than using 304....but i need to know where to buy a stainless exhaust flange to bolt to the head and also the turbo flange and radius plate....I found one site but it was all mild steel, just curious if anyone knows where to buy stainless...My dad is a proffesional welder so it wont be hard at all to do, if anyone knows of anywhere let me know....thanks

**Also what size diameter pipe is best to use, i was planning on either 1.5" or 2"**
