The VAFM on my 91 3.0 sounds like a tin can full of rocks being rattled. It's muffled and not too noticeable with the stock airbox/filter but when I tried to put on an intake w/cone filter it was hideously loud and obnoxious so I went back to the stock airbox/filter. Truck runs great, whats making the VAFM sound so crappy?

 

And because everyone loves pictures, here's a pic of my current set-up...

 

Only thing I recognize is the beer can. Everything is too clean. Nice mod
