Best estimates are appreciated. About how much hp does cai, 4-1 headers, muffler, cat, and throttle body add? Would like some estimations to go with before I go for a dyno.

10 to 20 tops...........cai about 8 header 2 0r 3, exhaust 5 to 7 T.B -you should get the intake manifold ported to match........CAT i duuno probably 2 or 3.......AFX udp 8 to 10 mostly throttle response..........In other words buy a turbo, (which is what i should have done)

or NOS..... hehe
