FN-B303 : Funtech 3DTE Muffler for OS105

This 3D muffler is designed for OS Max-105HZ and Max-105HZ-R.

Rigid type, same as 90-class, this muffler is designed to pipe in around 15,000 rotations. The opening of the exhaust port was designed as large as possible to release the exhaustive gas smoothly.

The expansion chamber volume has been increased. By torque-up in the medium to fast speed range, the full power of an outstanding tuned muffler is brought out.
