The GMP350 Replacement Muffler Insert may be installed in either direction.

NOTE:

Looking inside the muffler insert you will see radiused channels (or louvers). The installed direction of the louvers effect the sound level.

  • When the openings face downstream away from the engine, the sound level is slightly louder
  • When the openings face upstream toward the engine, more exhaust gases divert through into the fiberglass packing, reducing the sound level
