well ive heard my friends single in single out 50 series flowmaster and dissagree with it compared to my single in dual out 40 series flowmaster. Ive heard borla and that would be MY second choice and last resort would be magna.
i have a clip of my exhaust in my sig if you look down below more.
but i have to say its all in the layout of your pipes and how big or small you go in pipes. and your smaller mufflers are going to be louder. goodluck
haha btw you DID start another exhaust war NICE!!!
