I just picked up a stock 2012 V Sedan and need to pick a cat back. I had a Billy Boat on my 08 C6 and loved it! I prefer the deep tone as opposed to high pitched/Rasp. I also like gurgling and popping on decel like I had with the Billy Boat on my Corvette. Anyone have experience with both the Borla S-Type and Billy Boat? Or any feedback would be great! Thanks in advance!
