Hello All; As for sound, its noticeable.. Unbearable, not really.. Its only really noticeable under load.. Taking off, etc.. With just a soft-top you can barely here it going down the highway @ 70.. At least now it sounds like a jeep.. I will try to get some sound clips up this weekend..
Low RPM torque - @ 1650 it was averaging gains of 26.5hp / 25tq.. Not bad to me..
I don’t have any hook ups as for the parts. I paid full retail..
- $250 for the AEM
- $260 Jet Performance Stage II chip.
The exhaust cost me about $300 only because we tried both Dual and Single set ups..
My exhaust shop says it should only cost about $180 for the Single Magna Flow System..
Having the muffler relocated is nice because now I have all the extra room under the back for whatever I may come up with..
Just to give everyone an Idea of the Dual Exhaust setup.. @ 2000 RPM’s it actually lost HP and TQ over stock…

Very good, torque number are great and there is an improvement on the lower part of the curve. Are those number corrected ones. Stock, it should have 202hp and 237lb/ft , your stock number seems very close to spec? Thanks

Hey thanks again for doing all this work for everybody. Its good stuff that we can all use. If I woulda known the single exhaust would give better numbers cause the 3.8 likes the backpressure i would have gone with one. Oh well, the duals look badass. lol
