You should be able to order them from your local dealer or independent.

 

try v twin they have 2 in to 1, 1 3/4 head pipe 3in collector,with steel baffle comes with mouting bracket,part # 29-0144,or if you like stagered ex. you can go with,part # 29-0111,1 3/4 head pipe 2 1/2 muffler,the catalog lists these pipes for 85 to94 fxr evo motor but they will fit your bike,you have a late 84 evo motor, harley still had the shovelhead in 84 but in late 84 went to the evo motor,and many times when looking for parts for this year bike it will not list a 84 fxr,but if you need parts for it look for 85 up fxr parts they will fit, do you have the rubber mounted ex bracket with channel mount ex pipes? thats what is stock on these bikes and the above pipes will fit. if you need help with this bike just ask and i will help you as much as i can.

Try directparts.com or bikebandit.com. They both carry parts for the older bikes. I don't know about V-Twin. I've never really cared about their products. Most are imported like the stuff the stealerships sell and are of so-so quality.

 

UPDATE...
take a look at these, american made... hooker pipes, that are on ebay,comes with everything check it out...ebay item# 270010521543 the price is great for these pipes.
