About how much do you think it would cost to get my muffler and tips installed Lightning style or slanted behind the rear tires? What do you think about this setup? I ordered a Magnaflow 12518 muffler(14"body, 2.5" single in, 2.5" dual out) and 2 Magnaflow tips(12" rolled, 15 deg slant cut 2.5"in, 3"out). Thanks for the help.
