Na Tommy any good pipe bender could make them with the bike as a template,Jimmy Cox the best bender in London Ont. can make any pipe if you bend a piece of wire along the center line of what you want.Tell him what your putting it on and with out even seeing it he will make em right but thats what 40yrs of bending pipe teaches you I guess.
Dont right them pipes off Drew I have seen some prety thin pipes ceramic coated,jet coated ,come back to life.They dont need much to work with and once coated they never rust again, or blue,flow better than new.And done in black look great,silver is ok but looks like crapy fake chrome to me. As long as they can be diped cleaned down to metal without big gaping holes they can be coated.
Titianum pipe is expencive but dosent blue(well it does but can be claend back and only right at the exhaust port) or rust and gets a cool golden colour,the pipe on the Wr is 14yrs old and as good as new.But what the stock pipes are going for might not be anymore expensive for the small amount you would need Unk.Food for thought.
