I seriously doubt short shots will be a big power maker, but only the drum will tell for sure.
No one can really say what any particular bike will make in terms of torque and horsepower with only a pipe change; it will depend on many factors including what kind of numbers the bike produces in stock form as well as the quality of the tune and the pipes themselves. Some pipes on the market are designed to look good and make a lot of noise, not to produce good torque and power curves.
Stock bikes tend to run closer to 80 hp than 90hp, from what I've seen on many charts, and it would be quite rare for a simple pipe change to add more than 10%. There is only one way to know for sure, and that would be to have the bike dyno'ed in stock form to get a baseline, do the pipes and tune, and then compare the after numbers to the stock numbers. It seems that few actually do it this way, so they don't really know how much their choice of pipes and tune changed the numbers.
