Depending on where you are you may want to find a place to store them in case you may need them again. Doesn't the 2011 have the catalysts in the head pipes? I'd hate to even think what a replacement set would cost should for some reason you needed to revert back to original factory spec exhaust,,,ie for a state inspection or something.
No doubt you are right...I store them and will never need them...I get rid of them and will certainly need them as soon as I do so...I'll pack them away for now...Thanks!
