If those are the 1 5/8" equal lengths, I hate to be the bearer of bad news, but I wouldn't expect more than 5hp.
Your car doesn't need the extra flow that the equals will provide, and they'll rob a good deal of low end torque.
Honestly until you get some mods, you'll be much better off with the stockers. Even though they look like *** , they are not the bottleneck you want to address in the exhuast. That is your factory H-pipe. Swapping that with a hiflow unit could net you an honest 15hp.
