IIRC the blue AFE filter is oiled, & the others are not.
I've read to help remove the rubber hanger you can spray them w/a soapy water mixture.

I have always been a fan of CAI, I may give it a go, anything to help with my stiff pedal. I was waiting to see what K&N would come out with for the 2012. I do like the resonator to reduce/eliminate drone though, this may have won.

Love the looks of that Banks exhaust tip. Back in the day, we did our own cheap upgrade by simply ramming a large-diameter rod lengthwise through the stock muffler, angling as necessary from the inlet to the outlet. Instant freed-up exhaust, and it looked stock on the outside. It always sounded better, and didn't hurt the power according to the seat of my pants. Since you're throwing away the stock parts anyway, it doesn't cost anything to try. I think I'd still get that super-trick Banks tip tho...

Correction - UNCORRECTED?

Hey guys,

My brother was with me at the dyno, and brought to my attention that when he read this thread my numbers seemed low. I was using the SAE option in WinPEP as it seemed like the default correction. He was watching the figures on the screen while dyno'ng and advised that the overall numbers would be higher if we use the UNCORRECTED option in WinPEP.

Here is all run in UNCORRECTED format.

The overall power gains are close to the same as before, but the horsepower is higher.

Ive been driving with these mods on my truck for the last two day, (spent Sunday off road) and I dont really hear the exhaust unless im trying to hear it. In normal driving you can forget its there, until you hit the gas and it comes to life.

So you are saying that resonator eliminator on the CAI reduced your overall exhaust note?

The resonator eliminated Cat back exhaust didnt reduce my exhaust note (exhaust note - noise made by the exhaust), Im just stating that the exhaust is not overbearing. And you dont notice it unless you're accellerating.

The CAI (Cold Air Intake) is where the air goes in, and has nothing to do with the exhaust note or the resonator. The CAI makes the engine itself sing like you would not expect. And that noise is coming from the front, not underneith or behind the driver.

Completely understand that. I was going off the description on the Banks CAI from the provided link. It seems they are saying Engine Drone, which to me could be any noise from the engine up the the point of exhaust. CAI in my previous applications has never produced a drone that I know of.

This is from the Banks description here.

The huge inlet, enclosed housing and much larger tubing reduce restrictions, dramatically improving airflow to the cylinders. Another key element is the tuned "Helmholtz" resonator which eliminates engine drone while maintaining a throaty sound.

Sorry buddy, I misunderstood. I dont know what that resonator is, or what it does, I dont notice any drone from the intake. If anything, im trying to make the intake make more noise by hammering the throttle. When your not on the gas tho, the intake is quiet as a mouse.

So you dont hear a vacuum sound when driving at lower RPM's ? In the video of the test of the intake you can hear that Suction sound right as you stomp on the gas.

I ask becuase I had a CAI on a BMW that would produce a air sucking sound when i was at say 1500 rpm just driving along at 30mph. But above that it would go away, and sounded awesome once I was pounding on the gas pedal.

Exactly, I don't know what engine drone Banks is speaking of here.

You'll hear the Stage 2 Intake sometimes in daily driving, but its sublte. Once you get on the gas tho, its manners go out the window. Sucks like Mega Maid (spaceballs refrence)

I freaking love that thing.

Me either, I've never noticed anything w/my current CAI on my WK. I'm not sure about the "Helmholtz" thing either. I hope I didn't muddy up the AFE info by posting that Banks link. Is there a 3.6L specific thread, to post all available goodies?

I haven't really studied the dyno sheets but at a quick glance the AFE exhaust with the AFE intake makes LESS power than the AFE intake and the stock exhaust?

Torque stays about the same.

sounds great. that filter IS huge. cant wait to here about the mpg's. yep it will be hard with the cool new noise. i never listened to the radio in my cummins just cuz i loved the sound of the turbo.

torque climbs with the exhaust, but the thing you have to keep in mind, is that the air flow is different with each run... The cpu was confused with the new conditions each time, meaning the lean and richness of the way it was running was changing as we were dynoing.

What I mean is, the system didnt know how to use the extra air and less backpressure of the new components. I think its learning however, because my truck feels like its getting faster.

Maybe I shouldnt have done it all in the same day.

Im an awful mpg tester, im flooring it everywhere. Damn truck is so fun to drive with a little extra punch.

I was noticing the same thing. That would explain why AFE didn't post only the exhaust results in the dyno that they posted on their website. It could be as was mentioned earlier, adding only the exhaust provides some improvement, but adding the CAI to the equation nullifies the exhaust improvements.

I don't think I'd get the CAI because I'm paraniod about hydrolock. I do have the AFE exhaust that Pie tested because I wanted the extra offroading ground clearance. I'm hoping that adding only the exhaust hasn't caused my JKU to lose power over the stock exhaust.

Pie, do you have any plans to dyno your Jeep again after the ECU learns the new air map for your CAI and exhaust. I'm wondering if you will see additional improvements.

I'd like to see a dyno with just the exhaust, actually just their y pipe. I think that might be robbing the power.

I didnt install the y pipe because AFE advised that it was the same diameter as stock and was made for purposes of relocating the pipe so that lift kits could be installed.

You definatly get the offroad clearance, it a bunch of inches. The muffler is completely hidden by the back bumper. You can see in the sound video, the muffler has disappeared.

Its going to be in stock this week so I dont expect to be able to test both on saturday, You guys may have to wait another week for the second exhaust. But ill get you everything else this weekend as promised.

So in short, We are going to dyno-
AFE CAI 54-12092
AFE YPIPE 49-46215
AFE CAT BACK 49-46212
AND
AFE CAT BACK 49-46218

The Y pipe im using should keep the loop intact and should keep the exhaust "scavanging". (requires equal length pipes)
So you are just waiting on the other exhaust to come in? What is the exhaust you tested? It bolts to the "b-pipe" after the y?

If it does, it isn't enough to feel it. I have it and mine felt the same after as before...

I might be interested in just the axel back muffler. To get rid of the trash can sized one.

And ya , I got the oiled filter,, as long it isnt drenched like the KN I will be fine.

Otherwise Ill get the dry yellow filter.

It means that I put the y-pipe on my Jeep and didnt notice a difference(butt dyno), the only way to determine if it did anything would be to dyno it(real dyno).

I called AFE today and found out the Blue and Yellow filter are both oiled. Light oil.

The Light grey filter is Dry.

Between the Blue and Yellow. Yellow is offers more protection offroad, and the Blue is more free flowing ,, more for on road.

My filter is back ordered now,, but Im trying to work a deal on that with the axel back.

Good work Pie ! Nice setup.

Pie I just picked up the axel back and intake and they thru in a grey dry filter since they are back ordered! Intake should be here next week!

Cant wait!!
