You can use the Corksport Exhaust with the Curt Class 3 hitch #C13127, if the Racing beat is the same set up it should work too. The front hangar is not used by the C/S exhaust, so I just left the rubbers off...
LOL. I sent an email to Corksport, with pictures to verify the fitment, and they quoted my email on the comments of the webpage.. Here they quoted "cocksport" >.<
