Does anyone have a good source for design and fabrication of headers for the
rotary? I want to use 321 stainless X .065 wall at the inlet but what
practices should be observed as far as slip joint construction?  Do you
expand the tube to fit over the same size?  Do you purchase different size
tubes that telescope? What is the preferred design of the slip joint? Is
wall thickness
maintained throughout the length? Thanks for any help

One can get tube expanders to make slip joints.
Flanges are available from Racing Beat and Mazdatrix.
JC Whitney and or Warshawsky has SS muffler parts.


I would use .065" thick for the first couple of feet
and then go down to .049" thick.
Depending on the design.

I have a good fabricator on SS. Let me know what you want
and I'll do a dwg.

He has already built one muffler for me. He follows dwgs
and does not try to design it himself.
