Exhaust Deflector

The nylon tie wraps provided to hold a plastic exhaust deflector to the muffler frequently fail to work, with loss of the deflector during engine run. I fix the deflector in place with small screws. Position the deflector on the muffler at the desired angle, mark a spot and drill a hole. Remove the deflector and tap the screw hole, then install the screw, holding the deflector steady. Repeat at 180 degrees. I use a 2-56 drill and tap and 2-56 x 1/8-inch screws. I have not lost a deflector since using this procedure.
