A couple of thoughts here:
1. Has anyone tried using any kind of exhaust wrap? Will this deaden the droning at all?
2. Has anyone tried just cutting out the secondary cats in the stock x-pipe and welding in some resonators (in combo with a slip on?). This essentially gives you a 4-resonator "street" x-pipe.
