Where could the low drone come from when im on the freeway? I had a loud fart can that got me the ticket. So i picked up the world sport. It sounds real nice and low, but that deep low drone is still there. Could this be caused by the fact that my dc 4-1 is severely dented and my cat is hollowed out?

its definantly the cat. i have no cat(and no resonator) and it drones like hell on the highway. you should either replace the cat or have a resonator put it.

WS catbacks come with a huge resonator in the B pipe. Mine has that same drone. Being that your cat is hollowed and not a straight shot, I would say that is definitely going to change the resonance.
