So after reading through tons of threads/comments I have decided on getting the Magnaflow 19429 instead of the Borla Touring cat back since It seemed to be the "quietest" option and was also about 500 dollars cheaper vs.Borla/resonator. I noticed on Magnaflows website it has the street series as an aggressive exterior sound. How aggressive is it? I would have just gone muffler replace, but I need a new system since my exhaust is bent in a few spots.
