Very good value or money. outlet pipes are baffled and it certainly appears to be an acceptable sound level. I will post DB readings next time using the engine.

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.
