I think people open the exhaust up too much and the makes them sound bad. I have tog headers 3" dp, no cat, 3" resonator, 2.5" resonator both stainless works, then into two 2.5" borla mufflers. I have no raspy sound at all and pretty much no drone. I use to have a just one resonator a 2.5" magnaflow and it was complete crap. High quality resonators and mufflers seem to be only way to make them sound ok, other than turbo.
Id like to hear a GP and Regal with all the same exhaust, but the one muffler vs two
