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. Steve Brooks -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net]On Behalf Of Bulent Aliev Sent: Tuesday, August 15, 2006 5:39 PM To: Rotary motors in aircraft 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. Bulent "Buly" Aliev FXE Ft lauderdale, FL http://tinyurl.com/s5xw8
