It mounted to the motor via a Y-pipe. It then mounted to the motor studs (they run up through the white U-channel) so it was in the same vibration plane. The problem I found in flight (worked fine at full power on the ground) is that with the can extending far into the air stream the exhaust has too much pressure and was pushed backwards - stressing the mounting brackets to failure.</font></font></b> </p> <p><img src="6.jpg" height="252" width="378"><br> </p> <p><img src="7.jpg" height="192" width="196"></p> </center> <p><br> <br> </p> </body> </html>
