This is a tough call. But since we are comparing out of the box units, I have to do it as it is.

Ill tell you right out of the box, its RIPP by a mile. You can barely tell that the Magnuson unit is installed, as "out of the box" like we are talking here, you would put your stock intake back on. The stock intake silences the pentastar. Here are some soundbytes so you can see the difference from one unit to the other.

Here's the RIPP's sound bytes

First, here is the drive by sound. Black Betty sounds like a fighter jet on the road. The whistling pentastar sounds like a jet engine.

** Sweet Pea is in this video, but she is not supercharged at the time. We used her as the stock jeep.



Heres another one



Now for the Magnuson unit -



Just for fun, to show how terrible the stock intake is for muffling the fantastic noises that the pentastar engine makes, here is a video we did for the AFE Pro Guard 7 intake. You can hear the difference immediatly, and this is just the intake.



As far as crowning a winner with only the gear you get "out of the box" with your supercharger purchase, RIPP wins easily, once you put an intake on the Magnuson unit, it might be a completely different ball game. (ill do it for fun)

Sound Winner: RIPP
