bit new to this but I'm giving it a shot.... I own a '13 GT with a Borla atak cat back installed.. upon installing I've noticed with aggressive driving my mufflers tend to shift and rub on the bumper causing melting/damage... I've installed these right I'm assuming I just need to retighten somewhere? When driving with no wheel spin etc. I have no issues. Definitely an easy fix any advice would be great though, Thanks!
