Barker's or Monster's noise level?

What kinda of difference would a PCIIIusb and a FCI intake system make with the stock exhaust??

I ran with a Prodesign intake w/K&N plus PC3 for quite awhile.  It gives you a nice increase to low and midrange, and a little on top as well.  I also ran the Phoenix SA instead of the stock buttplug to let the stock exhaust flow a little better.

Got a link to that Phoenix SA??

I got one sitting in my garage if your intrested.

I ride Oregon dunes with barkers quiet cores and they want 93 db. I passed the test with a 94.(had to put the air box lid on) the officer let me go with 94.he said that was close enough. just got lucky I guess.
