Up front: recently bought flowmaster american thunder axle backs for my '12GT from American Muscle (AM). Install, no problem, start up, AWESOME sound albeit louder than the video demonstrates imo. Test drive...someone freekin' shoot me! Ugh, these things sound like the exhaust was blown right into the trunk! Took pics since the tailpipe looked recessed to me and not sticking out far enough to transfer sound behind the car. Contacted AM who conference called flowmaster. Tech said the pics did look like the tail pipes were recessed a little much. Suggested I try loosening clamps and reposition the mufflers but said they would "take care of it" if I wasn't happy. Did as instructed, still just crazy sound...and my hearing isn't what it use to be! Took em off the car after a couple drives, just intolerable for me! Called AM back, no real help from them so am dealing with flowmaster atm. No, this isn't an AM bashing thread, thread would have a lot more in it, believe me! So, I went back to review the video on AM site and comparing the video of stock vs. the flowmaster, in my opinion, it is far less quiet that the difference I hear from my stock vs. flowmaster. Just curious if anyone else thinks the same?
