hi i am looking for the stock marauder exhaust from the header all the way back o the tail tips plus the stock hangers and bolts? also i am seeking the best car audio speaker setup to make my 2007 base crown victoria sound good and have that clear deep base sound with out having the put all kinds of aftermarket amps and caps and thing like that?

also i need to know what size stock subwoofer is put into the premium sounding audio crown vic's? i have replaced my stock speakers with aftermarket but not really any clean base just a lot of voice which i hate!! i am looking for a setup for the cleanest most clear sound and base with stock sized aftermarket subwoofer speaker package that i can buy? no amount of money is the problem...
thanks
