Hatori SB-23FH Nitro Pipe Set (YS 120SR)
This is the Hatori SB-23FH Nitro Pipe Set. This tuned muffler has been developed exclusively for the YS 120SR. Maximum power is available in the 13,000-16,000 rpm range. When your rotor speed and gear ratio are set for 16,000rpm during cyclic load conditions, this pipe will allow the engine to hold the intended rpm.
NOTE: 16,000 rpm is the maximum rpm range recommended for this pipe. Operation at higher rpm's is not recommended and the increased vibration is likely to damage the pipe. This damage can be identified by the manufacturer and is not covered under warranty.
