Hi Buly,

I like the approach Al took on his Velocity and am planning something along the same lines.  A tangential muffler feeding a resonator.  I would like to make the tangential out of a nickel alloy such as Inconel and would need some 2" tubing, and 5 or 6" tubing (or sheet that I would form into a welded tube) as well some sheet for the end cap and transition.  I would like to use at least 16ga., but am flexible to price and availability.

The balance of the piping / resonator could be 321 (preference to Inconel, if I can find a source) 3 or 3.5" tubing, and 5 or 6" tubing.

Note: I use the Inconel trade name to refer to any high temp nickel alloy with a temperature resistance of 2000F or greater.

Thanks,
Joe

Joe,
What size and gauge? I may be able to help?

I am planning the exhaust for my 20B.  Does anyone have a good  source for 321, Inconel HX, Inconel 625 or any other nickel alloy  suitable for high temps.

Thanks,
Joe
