Talking with some of the racing buddies, I discovered a few things

about tuned exhaust systems. One trick is to paint the pipe with white
paint and run the engine.  Where the white paint burns off, is the point
of tuning. The pipe needs to be cut off about an inch after that. I
removed the PowerFlow muffler insert to do this, and replaced it with a
pipe, so I could paint it. I ran the engine, but could not find the
burnt ring. So go figure???<<<
Does this make any sense? Never heard of it.
