Thanks for sharing. If I rotated my wheels on the same day I would check to ensure that the lug nuts are tightened.A public service announcement (PSA) on how to get your Passport to sound like it has an AEM intake installed.
I had some maintenance service done this morning. One of the things that was noted on the paperwork was to change the OEM intake filter on or before the next service. I’ve been running the OEM intake system for some time now, had an AEM intake installed previously. As we were driving away from the dealership I was merging with traffic and gave the rig a good ‘ol foot stomp on the right side pedal. Right away the engine (intake) was much louder and I thought, “gee, that almost sounds like I have the AEM intake installed.”
We pulled over and I popped the hood. The service tech inadvertently did not latch down the intake box. (At least it confirmed he actually looked at the filter since you have to open it to see the filter condition.)
Anyway, if anyone wants to know what an AEM intake more-or-less sounds like, just unclip the latches for the OEM intake and take the rig for a spin. Make sure there’s a gap between the top and bottom pieces of the airbox.

AEM part 21-795C.What AEM do you recommend?
Excellent feedback! I'm itching to add some exhaust sound as well!All those are exhaust manufacturers or exhaust component manufacturers. All have PDF catalogs available for download. If I were building this I would buy both front and rear gaskets then compare measurements from catalog to each gasket. For what you want (I think) sound-wise I would go with a Magnaflow multi-chamber front muffler and either a dual chamber rear or straight-thru. Depends how much resonance you want. You need back pressure (chambers) on the front to slow down the sound waves (and not kill your gas mileage). The dual rear will deepen and soften the sound out back while a straight thru will have more high frequency wave (think whaaa). I prefer growl to whaaa but chose what you want. Use stainless mufflers and pipe, flanges will be carbon which will rust, unless you can find SS somewhere
