when will Borla provide official comparison sound clips of their exhaust systems( S type, touring) for the 2013 shelby I know there are a couple of videos out but it seems like each one has either x pipe or long tubes. What we need is a video of 2013 shelby S type and touring axle back in comparison to the cat backs no other mods so one can really make a decision. Looking place an order ASAP debating between those two. :??:
