I have the loud mouth with no muffler just a resinator. How much bennifit will i get from putting the cut outs after the cats when there is really no muffler even there? or would it be more benificial to put the cutouts before the cats right at the header joint? Thanks

 

if you dont have the muffled version, the cut-outs are only going to be a little louder, i would leave it as is.
