They will probably sound that way until they get broken in, but also possible they will not change until another set-up is chosen. Others not mentioning rasp, can be because of 2 reasons, everyone's hearing isn't the same, or they have a different exhaust setup than you do.
Certain exhausts (mufflers) sound different with long tubes/shorty headers, also the mid-pipe (x or h) play a roll in sound.
Exhaust is also subjective, just because someone else raves about it, doesn't mean that you will.
I received the verdict. There are numerous holes and seams in the welding. I am extremely disappointed in the quality. I would assume that MAC would do an air test and seal test as part of their quality process, but I guess not.
American Muscle came through with offering an RMA. I wasn't happy with the fact they offered to only pay half the labor to have the welds fixed. I choose not to do the welds because I purchased the ceramic coating to keep the aesthetics and I don't want the possibility for failed welds further down the line. On top of that, no one is going to reimburse me the cost of labor for install/uninstall/install. I am not a happy camper because it's a lot. I tried to reach MAC to see if I could just have the passenger side header replaced and save labor, but couldn't reach them at all, plus I have heard their customer service is notoriously bad. I called about ten times and only got the message that their voicemail services are full. Needless to say, I will never buy another MAC product again nor do I recommend any one else.
