You'll find the CAI's are more for looks and sound. You will get minimal gains from it. We actually have some guys trying stock & CAI's on the Challenger forum and running quicker times with the stock intake. Can't speak for which exhaust.
Intake and Exhaust upgrades
Looking for some suggestions on cold air intake and exhaust modifications that will add a little more power to my '07 Limited. I have the 5.7, and the only thing I've done so far is replace the old aIr filter with a K&N. I have been researching the various CAI's and will probably go with the K&N 63. I have also been looking for a cat-back system that splits the exhaust to each side of the rear, but all I have found are single exhausts and a side-by-side dual. Maybe I should just change the muffler. I love the deep throaty sound it has now. I am looking for simple DIY mods to increse HP, torque, and fuel economy. Any suggestions are greatly appreciated.

a cold air intake system will definitley help the overall power, and the sound on acceleration. as for the exhaust, you will notice an increase in sound with just a muffler. id get a whole catback (or even headers) to increase overall performance and sound. these mods together will add a nice number to he hp and tq. another mod to look into would be some sort of hand held tuner. you can go all out and get a custom tune, but with a mostly stock truck, it wont do much. as for the tuners id check out superchips, bullydog or hyper tech. another small, yet easy mod would be a ported throttle body.
other mods could include:
-spark plugs/wires
-thermostat
not saying this is true for every car/mod, but with my truck, it came stock with 235hp at the engine. im now running 235hp/293tq at the wheels.. so around 80hp at the engine (at that time, mods included: CAI, cat back exhaust, ported TB, super chips)

I'm running the VOLANT intake and love it since its enclosed with a large filter. I also just ordered Gibsons Axle Back System that was just released
