I haven't been around here in a while but I picked up a 2013 Boss about a month ago and the mod bug has already kicked in big time. I have already added an mbrp cat back and an Airaid cold air but now have on order Kooks 1 7/8 long tubes, off road H, aluminum drive shaft, 84.5 mm tbody, and the carbon fiber intake tube for the airaid because it was on indefinite back order a few weeks ago when I ordered the intake but now it is available to ship. I plan to have it custom tuned at REV auto.
