Sorry for the late response havent been on here in a while but to answer all questions, There's no resonator at all, and its the only thing other than rims and subwoofer done to the truck. (aside from the soon to be arriving ADD Venom Front and Rear bumpers) And for a heads up RBP dual wall tip makes it alot deeper than you would think but since im young and dumb i kinda messed the tip up and since i plan on sand pit playing again im going for turn down tips oh and about a month after having the exhaust it got really really loud alot louder than in this video im gonna post an update video when i get the turn downs put on hopefully in the next coming week.
