Does anyone know if the GYT-R insert for the WRF 450 will fit the YFZ???????? It works on all the WR bikes (250F,426F,450F) Said to really help out lots with the stock pipe......... supposedly about a 5.5 overall increase in HP..... That would be sweet if it would work with the YFZ.......... Not quite as loud as an aftermarket pipe but a little boost in the goodies....
Let Me Know

The insert for the WR will not work in the YFZ. The pipes and inserts are different.

GYT-R is making a quiet insert for their GYT-R Muffler.

Hope that clears it up.
