皮茨消声器20cc的发动机 - 尼斯质量皮茨消声器，比股票消声器，适合苗条整流罩，飞度的RCG 20cc的发动机更安静。
when fitting this exhaust to the RCG 20 in the HK Grasshopper you will need to cut a large hole in the firewall to accommodate it, use the pitts muffler for the 15cc engine instead it's slightly smaller and fits to 20cc motor perfectly.Port 16.5mm x 10mm, Bolt hole diameter 6.3mm ie 1/4" outer bolt hole to outer 36.5mm, inner to inner 23.5mm.
This fits my RCGF26BM perfectly, the manifold face plate is the same as the on on the original muffler as far as I can see and the supplied gasket is also the same size.
The 2 tubes have 16 hols drilled in them in rows of 4, 90 degrees apart.
Im a bit concerned about the over sized hole for the bolt but then the original muffler was the same.this muffeler is not for 20cc ,may be for 35cc ,cause each exit hole diameter is 16mm whereas dle 20cc muffeler has one exit hole diameter 14mm.i bought this and tried on my dle 20cc.my engine is not working properlyUse it with my HK 20cc and its for sure much quiter than the orginal silencer. Very pleased and no issues so far after a few hours of running.
