Buly,
That looks like some mighty fancy welding.  Did you do this yourself, or
have a shop weld it up for you ??

If you had a shop weld it, I was wondering how in the world they would get
the pieces to fit correctly.

It looks pretty nice, and it will undoubtedly last a little longer than
Joe's ABS exhaust.

Subject: [FlyRotary] New NA exhaust finished


After almost 3 weeks, my new 2 pipe straight out exhaust is finished.
It is made of 2"  321 stainless tubing. At the end they converge into
one short 4" oval tube. The fancy bends are to make the inside length
the same for each tube. The flange is Racing Beat mild steel. Each
tube has one EGT sensor about 3" away from the exhaust port. The O2
sensor is on only one of the tubes due to lack of room.. My biggest
concern was the noise that it was going to make. I was pleasantly
surprised when I started it in the hangar (John Slade told me it is
OK to do it :). The noise was almost the same as with the turbo
housing on. Saved 30 pounds of weight on the engine and maybe 10
pounds less of ballast on the nose. Did not have time to run the
engine at full tilt, since I'm in the process of making stainless
steel heat shields.
