I'm looking to get an exhaust system for my 16 2SS NPP. I'm going to go with Stainless Works, still deciding between the Redline or Legend, but not sure whether or not to go axle back or cat back. Is the cat back going to require a tune or can I get away without? Is the cat back louder and just how much. I want it to be about the same sound level as the stock NPP exhaust in track setting when the new system is in the quiet settings.
