AFE intake, Magnaflow Exhaust, and see what that does for you. If it isn't enough go with a tuner of choice. An engine is an air pump so the more you get in and out the better it will run.
And if that still doesn't get you up the hilss like you want to go then add a procharger! :D
Don't waste your money on an intake or exhaust. All that will change is it will be noisier. Your engine has electronic controls that only allow it to use as much air as it needs. Making more available won't change anything. The companies that sell this junk always start their claims with "adds as much as". If it was this easy to make more power the factory Engineers who designed these engines would use it.

While what you wrote is your opinion it is completely wrong. The electonic controls you speak of can and do get altered with a programmer. The reason manufacturers don't use higher grade intakes and exhaust is usually a cost vs. return for a whole line of products. I can guarantee an improvement in both HP and TQ as I have dyno'd my truck with the simple additions listed and now have 65 more HP and 100 Ft/lb. on the ground than the orginal setup made at the crank.
This. I have done enough tuning on the Trans Am and Truck to tell you computer controlled cars do respond well to just intake and exhaust.
The 2000 OBD II Trans Am I own with air box silencer eliminated, spoken installed CAI, and catback with no tune returned 24 HP and 31 Ft/lbs of torque at the wheels. The computer will adust for this extra air and add fuel. Hence the MAP/MAF and O2s. The computer can't stop the extra air coming and going, so it adds fuel and adjust timing. How do you think people like me get gas motors that run 13 second 1/4 miles stock to run 11 second 1/4 with no power adders(turbo/blower/N20) They add Air and fuel. Hearders, exhaust, intakes, heads anything that get more air in and out.
My truck with just a tune netted 15 hp and 10 ft/lbs of torque at the wheels. (2002 2500HD 6.0/4L80E)
Both were tuned on a Mustang Dyno.
Rules of thumb for drivetrain loss in these two are as follows.
The Trans Am loses about 16 to 18 percent through the drivetrain because it is a manual.
The truck loses about 18 to 20 percent through the drivetrain because it is an Automatic.
This is true for most massed produced vehicles. There are some that do much better. Plus some of the new stuff is even more effiecent
Your Hemi is similar to an LSx (LS1, LS2, LS3, 5.3, 6.0 well you get picture) The proper aftermarket intake and exhaust will net gains even without a tune. A tune will help to get the most out of it reliably. You many not see huge gains but you will probably see about 30 hp and 40 Ft/lbs of torque at the wheels. Which in the skeem of towing may not seem like much but every little bit helps!
Everything you buy is built with warranty in mind and being a good choice for a large section of the population. Engineers and Bean counters know this, so they leave the loud more H.P./Torque products to the aftermarket.
