have heard that when u put triple pipes on a 700 sxr u can put a srx rear heat exchanger on to help with the cooling but the nipples on the rear heat exchanger are bigger what to do now? 
any help would be great thanks ron

You need to go to a hardware store and buy two hose adapters[one for each side] that step the size up from your current rear exchanger hose size to the SRX inlet size. You will also need a length of heater hose that matches the large end of the adapter and joins it to the new SRX exchanger...a couple hose clamps /side will be needed as well.
if you just use the stock srx/viper hoses for the rear, you can use an automotive style clamp to shrink it down or you can cut a piece of the smaller hose to act as a bushing inside the larger hose. If you have only the small hoses, you need the larger ones. I have some if you don't, pm me if you need them.
also, check your sleds heat exchangers from one side to the other under your feet. I have seen lots of sleds with one full, and one half width style on the same sled, lots of extra cooling in that upgrade as well
