I have a 2006 LS V8 and I'm looking into replacing my stock mufflers while keeping the resonators intact. I'm having difficult time finding any full throttle takeoff or flyby videos of flowmaster/borla/magnaflow mufflers installed with the stock resonators still on. Most people seem to remove the resonators and weld an x-pipe. I just want to replace my mufflers. Any videos and/or insight would help, thanks!
