Gentlemen:  After 160 hours, I am working on MORE POWER again.  I took off the home-made muffler, and had the local muffler shop make me a 2 into 1 straight pipe so I could get an idea what the back pressure was costing me.
 
First off, it is so loud (just like others have reported) that I could barely hear the radio over my ANR headset!  I think an hour at full throttle would make you crazy.
 
Static rpm increased only by about 50 rpm, but on the top end, it made a large difference.  My normal WOT true at 3000 msl is 180 mph.  With the straight pipes, it was 206 mph!  Look out Tracy!
 
Muffler is back on, and the intake is the next project.  Need to make it more like the ones that work.  (Tracy, Ed, etc.)  I keep hanging that turbo on there, but it needs about a 2 inch spacer between the manifold and turbo to clear everything.  I am not sure I want 35 lbs hanging on the side either.
