HP gains from exhaust...25HP?

I was reading the faq on best bang for the buck and it stated that exhaust gains less headers could gain 25HP. It also said exhaust, headers and a raised top good gain 75HP. Thats a significant gain. Has anyone actually seen these HP gains with just freeflowing exhaust/headers and a top? Just curious because since I just got my exhaust done, I am looking for my next mod after my suspension (probably going to do eibach/bilstein combo). Probably some kind of cold air intake (still running with the stock air box/filter and silencer for the moment)
 
My first mods were headers, SCP exhaust with 3" center pipe, raised top and a 5% pulley. I got a little extra power on the top end with the exhaust, maybe 15 HP. The pulley and raised top probably added another 15.

Rule of thumb, cut all HP claims in half and when you add them all up you will still be guessing high when you go to the dyno.
