As for the intake use the aFe intake. It has the highest PROVEN dyno results of all the intakes. Plus it sounds COOL too... As for the Exhaust the magnaflow is a pretty good set up, but the Flowmaster sounds good too. Just be known, that it WILL sound like a Pontiac Grand Prix after you do exhaust..... The exhaust on the JK models is a really good design, and there is not alot of HP to be found there. I suggest GEARS. 5.13 gears I just wish they had something deeper than 5.13 gears for those of us with 37's, soon to be 40's..... However, the 5.13 gears work incredible with 35's.
