anyone put twin pipes on a 700 pro x ?who makes a set that fits good and makes power?also would i need to change the head to run pump gas with twins like the 800 prox.i was looking at the dyno port pipes which i have had good luck with.

I did a lot of research and the SLP single seemed like the preferred choice. More mid range and much less finicky.

We have 2 sets of LRM pipes for 700. Trail pipes (twin pipes with can) produce 140 HP dyno. Race pipes put out 149 hp dyno. Motor is totally stock in both cases. This is pto hp not track hp.

P.S. Trail pipes are not finiky at all runnig 92 octane.

P.S.S. hp reading on race pipes was with 100 octane still VERY finiky.

could you give me their address and phone number

HTG has some specific 700 twins that are supposed to work pretty well too. The SLP 800 ones also work well, but I've only used them on a ported 700.
