Ed--do not fasten it to the plane. = As your engine settles this will change the angle of the exhaust, if attac= hed to the plane it will rip out or the exhaust will come lose at the end.&= nbsp; The only connection of the exhaust should be directly to the engine a= nd each section of the exhaust to the other exhaust pipes.
