That seems like a fine idea, however he’ll still have the carpenter head and rest of the top end on the bike. Be kind of funny to not have the matching exhaust to go with that set up. Either way, nice pipes and nice bike. Good luck with the sale.
When I sell my carp bike the exhaust will be replaced by the TORs I have wrapped up waiting on the day
