pics worked.
see, the stock ends on the original pipe doubled as the expansion chamber and muffler, those you have appear to be just mufflers
 
the banshee pipes i got im hoping can be retrofitted pretty easy as im not a master fabricator. but trial and error can always be fun.
 
Get some real chambers on there, then decide you need more. With stock pipes it made about 40hp. Lucky if it makes 20 with no pipes. Also you need larger air cleaners, it will never breath with those little things.

FYI , RD is air cooled and does not have PV's. The RZ is water cooled and does have PVs
 
i have been trying to get ahold of passion racing to check into pipes i think he may be on vacation no answer. i honestly didnt think about the air cleaners, good point though. i think im gonna try to retrofit as much as i can off a banshee those parts seem to be plentiful
