Might be a long shot, but I'm torn between the Borla S and the Atak listening to almost every clip I can find on the web. Anyone somewhat local to the Philly area? Would love to actually hear it in person prior to ordering. My neighbor has a Hellcat Challenger...wondering if the Atak would be louder or quieter. I wouldn't want it to be much louder, but ok if equal since he already wakes up the neighborhood each morning when he leaves for work.
