Yes !! I installed a Coffman's exhaust on my 750ss and another on a 750Xi. The pipe yields good results in both cases. On the SS the effect wasn't nearly as noticeable as on the Xi. I guess the fact that the SS was a single-carb made a big difference. On the Xi, I immediately felt the engine revving easier and faster than with the OEM exhaust. I played around with the jets on the carbs but the ***-dyno tells me I could have left them as-is and it would have had the same effect on performance. All in all, the Coffman's setup is a great part to put in the PWC. The kit sounds awesome, fits perfectly, saves you A LOT of weight by replacing the huge and heavy OEM waterbox, and of course, delivers the performance increase we all want. Go for it !!

did you have the one with the electronic water injection or the original Hurracane system
I've actually fitted mine now and has some more top end and I still need to install the advance plate
