I might buy a used JBA exhaust and I was wondering if anybody had these 2 at one time. I just want to know which one is louder. I own an 07 and I just swapped out the stock muffler with the 18" magnaflow and put on a single dual tip. I know the JBA is probably not as loud as the Banks that I had on my 04. So if anybody can tell me I would gladly appreciate it.
