Good morning Ed,
I should have mentionned that you gave me the idea for the exhaust sound
suppressor inserts. Sorry I forgot to mention this.
I have to say that the rotary exhaust is even more powerful than I thought,
especially since I lenghtened my exhaust pipes to 31" minimum.
Let's see...the shortest pipe is 31" long. The inserts are ~7" long and they
fit into the collector, up to its crotch?. So the closest insert is about
24" from that exhaust port, while the lower insert is about 28.5" from the
other exhaust port.
