Here is a quick photo chop I did up of your original 100% stock run added to your best header/exhaust/CAI run. I've edited the bottom scale to try to match the two differnent layouts. But The torque scale is differnt on the two...so just ignore the torque, an stick with the HP, and you can see the gains. It is not a very accurate representation, but it is somewhat close...

Keep in mind the HP addition with the 4-2-1 header will not be as great with the 4-1's. This is due to the design. The 4-'1s are for higher revs while the 4-2-1's are for overall rev's. The 4-2-1 you will feel more than the 4-1's. If you plan on drag racing alot and want better ET's and trap times go with the 4-1's. If you do alot of road racing go with the 4-2-1's. zIf you know the major difference between turbos and supercharger. Think of the 4-2-1's as a super charger and the 4-1's as a turbo. Use a supercharger if you will be on and off the throttle alot and the turbo if you plan on drag racing. Like a supercharger your car will feel like it has a bigger engine with a 4-2-1 header. A turbo however will add top end but not a better throttle responce like a 4-1 header.
