hahaha i dont think heavy towing and 300s should even be in the same sentance lol. you have bd tow twins now? might want to upgrade to their r700 twin kit that will be your best option you might be able to do some towing with that. i see youre from alabama (not too sure about the landscape down there but i think it might be a little flatter than up here so that will help).
id upgrade to the bd r700 tow twins and then ditch the bd sticks for a nice set of mach 5's or 6's andif you dont want to go with those machs then find some nice 220-250hp injectors
