Just got a smokin deal.
With my DSP, Airaid MIT and Magnaflow cat back, I'm pushing around 1150hp. Unfortunately, after passing thru the 545RE transmission, I'm getting about 175hp to the rear wheels 
The stock air box does a good job of suppressing noise. Other than hearing a faint sucking sound at idle and low rpms, there is no moaning sound at WOT that I can hear over my Magnaflow talking to me. With the stock exhaust, it may be noticeable.
It looks nice and seems to help a bit, although, after removing the Hemi Hat, it didn't look restrictive to me except for maybe some turbulence from the holes going to the resonator.
Oh and the BFI looks like a standard issue Ricola horn to me. Designed in Switzerland perhaps? Still funnels down to the same size TB.
