and if so do you mean his exhaust or any v6 exhaust thats on a fairly stock motor? cause i know i got more than 2 hp out of my 2" true dual exhaust.
You can't add it up. HP is ultimately determined by airflow, fuel and cam.

If you don't change the cam, the MOST you can pick up from a CAI and dual exhaust is 17-20 in the BEST of conditions. And that's for a 99+ car, for a pre-98, it'll be 20-25% less because the engine simply cannot flow that much air.

CAI may get you anywhere from 5-12 hp, depending on heatsoak, quality of filter, and flow.

2" is perfect for exhaust tubing, you lose a lot of hp & tq when you install 2.5" exhaust pipes or larger.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
