When I got my 85'1300 the previous owner put these helix-dunstall pipes on it ,but was obviously in a hurry to throw em on the bike !
Looking at these stock brackets that came in the box ,mounted on the OUTSIDE drove me NUTS ! I believe that mounting brackets should be out of sight ....so I fabbed my own.
The new brackets are installed to the inside and making the appearence MUCH better !
I spent the winter months disassembling and cleaning/painting.....well worth the effort !
The pipes are a bit louder than stock but not annoying....actually they have a very "SWEET" tone ! very unique especially behind 6 cylinders !
