As for power you get a tiny bit of top end power. But you get a wide power band increase. Like the engine hits 30 hp at 7000 rpm instead of 8500 and is still making power out at 12500 before dropping off.
Of corse ignition carb work full exhaust is also kinda going along with it. They are actually heavy compaired to stock a couple grams but I found on the last engine this was good.
I love them but it is a couple hundred dollars and if you race check the class rules
