[MOTORHEAD]

I had made the joints tighter to seal a percieved air leak causing a lean backfire on closed throttle deceleration. I used an aircraft tubing beader and the Accustiseal.
Sometime later, I needed to remove that sidepipe. It wouldn't budge !
In desperation I disconnected the rear mount and gently using the pipe as a lever, moved it up & down, in & out, and that broke the slip join free.
