Can you just Get 2 Good Mufflers (HKS, APex'I, Greddy, etc) and Do a Custome 2.5" Mendrel piping for Dual Back, you can get that all done for a better look + sound for less than the price you would pay for the axle back alone?
My friend bought a set of Bombz EVO Mufflers on Ebay and get them hook on, they sound great, much loud with the Catalytic Converter Removed
