To compare somewhat, I have JBA shorties, hiflow cats and a "conservative smog tune for Kali". Peak hp is 32 at5600, peak tq is 24. At 6100 rpm hp gain was 44.Dyno was done on a 86 degree day and couldnt get anymore out of her. Other friends at same shop got similar results ans tune was about 10-12 hp of the gain, so 20 or so for the headers and hiflows.

I have jba shorties with solo hi flow cats. I like the combo....sounds really good with a nice bump in power.
