This is an aluminum exhaust pipe mount used in the conversion of a GEN 5 and GEN 6 Honda chassis to accept a 1989-2001 CR500 engine. 

This mount is made of 6061-T6 aluminum. It is cut on a CNC lathe then de-burred in a media tumbler. It is intended to be welded to the frame just below the water pump. It employs the stock rubber-isolated pipe mount that is normally used to mount the tail of the exhaust pipe(see images). The stock mounting part is not included in the auction, just the custom round part that welds to the frame. This mounting method is the only method that I have found to successfully prevent the pipe from ratteling against the water pump on a CR500 aluminum frame conversion.


This part is compatible with the following chassis:
13-17 CRF450R
14-18 CRF250R
